Chapter 14 Laboratory: Gas Chemistry 267q: 3 At 25°C, the vapor pressure of acetone is about 26.67 kilopascals. Can this information be used to increase the accuracy of your
calculated molar mass of acetone? If so, how?
q: 4 What modifications could you make to this procedure to reduce experimental error?
q: 5 Propose a method using only the standard laboratory equipment listed in Chapter 3 for determining the molar mass of carbon
dioxide gas. What change to your proposed method would you make if you had a vacuum pump available?
q: 6 If your sample had been unknown, would you have been able to identify the substance from the molar mass you determined
experimentally? What other datum you obtained could be used to confirm the identity of the sample?
