A saturated gaseous organic molecule is formed by replacing all hydrogen atoms with an unknown combination of F, and Cl atoms. The percent mass of Cl in the organic compound is 57.0%. Suppose that a sample of this gas weighing 0.270 g has a volume of 35.76 mL, a temperature of 23.2 C, and a pressure of 754.6 mmHg. Assuming ideal gas behavior determine the molar mass of the gas and its molecular formula.
