A plastic bag is weighed and then filled successively with two gases, X and Y. The following data are gathered: Temperature: 0.0°C (273 K) Pressure: 1.00 atmosphere Mass of empty bag: 20.77 g Mass of bag filled with gas X: 24.97 g Mass of 1.12 liters of air at conditions given: 1.30 g Volume of bag: 1.12 liter Molar volume at STP: 22.4 liters Reference: Ref 5-6 The bag is emptied and refilled, successively, with gases X and Y, this time at 1 atm pressure and a temperature 30°C higher. Assume that the volume of the bag is the same as before. Which one of the following statements is wrong? Select one: a. The full bag contains fewer molecules of each gas than it did at 0.0°C. b. The ratio of the density of gas Y to the density of gas X is the same as at 0.0°C. c. The molar masses of the two gases are the same as they were at 0.0°C. d. The mass of each gas filling the bag is now 303/273 times the mass held at 0.0°C. e. The average velocity of the molecules of gas X at 30°C is higher than it was at 0.0°C.
