See also our theoretical yield calculator for chemical reactions (probably your next stop to finish the problem set). (Boiling point of butane is -0.8C / 30.5F, and thus, butane is present as liquid below this temperature) The output density is given as kg/m 3, lb/ft 3, lb/gal (US liq) and sl/ft 3. The molar mass of C4H10 (Butane) is: 58.124 grams/mol. Overall, the percent error of this experiment was small, which indicates that there was high accuracy in the calculations as well as very minor presence of systematic errors. The calculator below can be used to estimate the density and specific weight of butane at given temperature and atmospheric pressure.
Possible answer: Because the butane will not dissolve in the water, it is possible for butane gas possible to form under water and get trapped. Pre-lab questions Possible answer: Butane is extremely flammable and will ignite. In addition, there is a chance that the water could have got into the lighter while the butane gas was being released in the large test tube, effecting the final mass of the lighter. the cylinder, which, along with the mass, will provide you with an experimental molar mass for butane. This suggests there is a possibility that the calculations obtained through the measurements from the electronic balance may not be entirely accurate, effecting the results of the experiment. For example, the electronic balance has an uncertainty of ± 0.01g, and is used to measure the mass of the butane lighter. Although this error is quite minor, it is most likely due to uncertainties of the materials used in the experiment. As a result percentage error of 1.04% was calculated. This is very similar to the actual molar mass of butane which is 58.12 g/mol. Based on the experiment and data analysis, the molar mass of butane was found to be around 57.52 g/mol. Conclusion The purpose of this experiment was to determine the molar mas of butane gas.
