TERACTIVE EXAMPLE Calculating the Molar Mass of a Gas from P, V, and T Data You are trying to determine, by experiment, the formula of a gaseous hydrofluorocarbon compound you made to replace chlorofluorocarbons in air conditioners. You have determined the empirical formula is CHF₂, but now you want to know the molecular formula. You therefore do an experiment to determine its molar mass and find that a 0.100-g sample of the compound exerts a pressure of 73.5 mm Hg in a 247-ml container at 23.0 °C. What is the molar mass of the compound? What is its molecular formula? Enter the elements of the formula in the order C, H, F. g/mol Molecular formula-
