A large evacuated flask initially has a mass of 134,567 g. When the flask is filled with a gas of unknown molar mass to a pressure of 735 torr at 31 °C, its mass is 137.456 g. when the flask is evacuated again and then filled with water at 31 °C, its mass is 1067.9 g (d H2O = 0.997 g/mL). Assuming the ideal gas equation applies, calculate the molar mass of the gas. O 69.6 g/mol O 36.3 g/mol O 1.3 g/mol O 45.2 g/mol
