1-Butanethiol, also known as butyl mercaptan, is a volatile, clear to yellowish liquid with a fetid (extremely foul-smelling) odor, commonly described as "skunk" odor.In fact, 1-butanethiol is structurally similar to several major constituents of a skunk's defensive spray but is not actually present in the spray. A common request on this site is to convert grams to moles. Index. The SI base unit for amount of substance is the mole. This large percentage of error is likely due to a variety of … NIST / TRC Web Thermo Tables, professional edition (thermophysical and thermochemical data) Butane C4H10 Molar Mass, Molecular Weight. It is used as a petrol component, as a feedstock for the production of base petrochemicals in steam cracking, as fuel for cigarette lighters and as a propellant in aerosol sprays such as deodorants.[14]. Next, the mass of the butane displaced was divided by the moles to finally give the molar mass of the butane. The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. The calculator below can be used to estimate the density and specific weight of butane at given temperature and atmospheric pressure. Butane is also used as lighter fuel for a common lighter or butane torch and is sold bottled as a fuel for cooking, barbecues and camping stoves. [18] By spraying butane directly into the throat, the jet of fluid can cool rapidly to −20 °C (−4 °F) by expansion, causing prolonged laryngospasm. Butane (C4H10), also called n-butane, is the unbranched alkane with four carbon atoms, CH3CH2CH2CH3. This site explains how to find molar mass. 0.20g/0.00352moles= 56.81 g/mole= molar mass of butane gas. The number of moles of butane can be calculated from the ideal gas law using the corrected gas pressure, water temperature, and volume from the table. [15], As fuel, it is often mixed with small amounts of hydrogen sulfide and mercaptans which will give the unburned gas an offensive smell easily detected by the human nose. The molar mass is defined as the mass, in grams, of 1 mole of any element or compound. common chemical compounds. Barometric pressure: 755 mm Hg, 0.994 atm 3. Show your calculations below 4 The molar mass of butane can be determined by dividing the mass of the gas by the number of moles in the sample. In this way, butane leaks can easily be identified. While hydrogen sulfide and mercaptans are toxic, they are present in levels so low that suffocation and fire hazard by the butane becomes a concern far before toxicity. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. of a chemical compound, More information on Name: Butane. Normal butane can be used for gasoline blending, as a fuel gas, fragrance extraction solvent, either alone or in a mixture with propane, and as a feedstock for the manufacture of ethylene and butadiene, a key ingredient of synthetic rubber. Aim: To find the molar mass of butane, by finding the number of moles of gas in the container and comparing it to the mass of butane in the container. EVALUATING THE PROCESURE (S) – A random error is caused by variability in samples. [10][11][12][13], When blended with propane and other hydrocarbons, it may be referred to commercially as LPG, for liquefied petroleum gas. The reason is that the molar mass of the substance affects the conversion. gal; 107,000 Btu/U.S. Introduction. experimental molar mass for butane. This is significantly higher than the actual molar mas, with a percent error of over 400 percent. In addition, you will make measurements of both temperature and pressure. Water bath temperature: 22° C, 295 K 2. so the molar volume at 18.1 C is 0.120/0.002448 = 49.0 L/mol (this is rather large - your data is not very good) The accepted value of molar mass of butane is 58.124 g/mol, and our average calculated value of the mass of butane is 56.57g/mol. When oxygen is plentiful, butane burns to form carbon dioxide and water vapor; when oxygen is limited, carbon (soot) or carbon monoxide may also be formed. You can find the actual lab if you search for it on my channel. Procedure. Its only other isomer is … Preparing the lighter. In this video, we will be doing a lab using the Ideal gas law.

In this video, we are going over the post lab for the molar mass of butane lab. n-Butane is the feedstock for DuPont's catalytic process for the preparation of maleic anhydride: n-Butane, like all hydrocarbons, undergoes free radical chlorination providing both 1-chloro- and 2-chlorobutanes, as well as more highly chlorinated derivatives. Hydrogen combines with oxygen to make water which is essential to life. Show your calculation below. Introduction Using your knowledge of gas laws, you will design and carry out an experiment in which you collect a volume of butane gas from a lighter by water displacement. ...2013 Molar Mass of Butane: Applying the Gas Laws 1.Water bath temperature: 17.7° C or 291 K Celsius to Kelvin temperature conversion: 17.7° C + 273 = 290.7 Kelvin (rounded to SF= 291 K) 2. The molar mass of the butane gas was calculated by dividing the mass of butane gas in grams (0.20g) by the moles of butane gas (0.00352 moles). The name butane comes from the roots but- (from butyric acid, named after the Greek word for butter) and -ane. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. Butane is a highly flammable, colorless, easily liquefied gas that quickly vaporizes at room temperature. Because the molar mass of the gas was less than the actual molar mass, it can be assumed that the calculation is pretty accurate and that the molar mass of the butane is larger than the other gases. The system operating pressure for butane is lower than for the halomethanes, such as R-12, so R-12 systems such as in automotive air conditioning systems, when converted to pure butane will not function optimally and therefore a mix of isobutane and propane is used to give cooling system performance comparable to R-12. Finding the Molar Mass of Butane Preparation. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. The maximum adiabatic flame temperature of butane with air is 2,243 K (1,970 °C; 3,578 °F). Goals and Objectives. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. Butane canisters global market is dominated by South Korean manufacturers. The relative rates of the chlorination is partially explained by the differing bond dissociation energies, 425 and 411 kJ/mol for the two types of C-H bonds. [17] Butane is the most commonly abused volatile substance in the UK, and was the cause of 52% of solvent related deaths in 2000. Volume of gas collected: 100.0 mL 4. This shows that there must have been other gases besides just butane in the lighter fluid. Butane is C4H10 - it has a molar mass of 58g/mol so you have 0.142/58 = 0.002448 mol of butane (this is not in your calculations though you do use the correct # mol - how did you get it?) [16] Contaminants are not used in fragrance extraction[clarify] and butane gases can cause gas explosions in poorly ventilated areas if leaks go unnoticed and are ignited by spark or flame. How is molar mass determined and how is the molar mass of an unknown found? [citation needed] Most commercially available butane also contains a certain amount of contaminant oil which can be removed through filtration but which will otherwise leave a deposit at the point of ignition and may eventually block the uniform flow of gas. Finding molar mass starts with units of grams per mole (g/mol). Molar Mass: 58.1222.
