Question 5 An empty flask weighs 129.504 g. After vaporization of a sample of volatile liquid at a temperature of 99.7 °C, the flask was sealed, cooled to room temperature, and found to have a mass of 129.879 g. The atmospheric pressure was 760.9 mm Hg. The flask was rinsed and completely filled with water at 22.3 °C. The mass of the water-filled flask was determined to be 377.333 g. What is the molar mass (in g/mol) of the volatile liquid? (Enter your answer as a number without units.)
