Interactive 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 71.0 mm hg in a 255-ml container at 22.9°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.
