A glass vessel has a mass of 53.8718 g when evacuated (no air). When filled with a liquid of density 1.319 g mL-1 it has a mass of 255.7390 g and when filled with an unknown gas at 752.3 torr and 16.12C it has a mass of 54.2483 g. What is the molar mass of the gas, express your answer in scientific notation.?

...i'm confused about the three masses given. from the equation P=d(RT/MM), you dont need mass at all. please help?
