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
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?
a). the molar masses of the two gases are the same as they were at 0.0°C.
b) the mass of each gas filling the bag is now 303/273 times the mass held at 0.0°C.
c) the ratio of the density of gas y to the density of gas x is the same as at 0.0°C.
d) the full bag contains fewer molecules of each gas than it did 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.
