the formula of an unknown compound with was determined in the following way : First, a sample was analyzed by element, and found to consist of 54.55% carbon, 2.27% hydrogen and 43.18% fluorine by mass. Then a separate experiment was done in which a sample was vaporized in a 292 mL container in a water bath at 100 degree Celsius. At this temperature, the gaseous sample had a pressure of 745 torr and was found to have a mass 1.234g.

What is the empirical formula of this compound? What is the molecular formula?
