Fluorination of acetone, C3H6O (substitution of fluorine for H) produces a gaseous compound with the formula C3H6?xFxO. To identify this compound its molar mass was determined by measuring the gas density. The following data were obtained: Mass of gas, 1.53 g; volume of flask = 264 mL; pressure exerted by gas, 722 mm Hg; temperature, 22 °C. Calculate the molar mass from this information, then identify the molecular formula.
