1. For a liquid (at 100oC) whose empirical formula is CH2, the atmospheric pressure was 0.9937 atm and the flask had a volume of 262 mL. The empty flask weighed 96.197 g and it weighed 97.6342 g with the condensed liquid droplets. Determine the molar mass of the volatile liquid and its molecular formula.

    Could someone assist me with this question? In the 19th century, J. B. A. Dumas devised a method for finding the molar mass of a volatile liquid from the volume, temperature, pressure, and mass of its vapor. (next column). He placed a sample of such a liquid in a flask that was closed with a stopper fitted with a narrow tube, immersed the flask in a hot water bath to vaporize the liquid, and then cooled the flask. Find the molar mass...
