Question

Consider separate 1.0 L samples of the following gases at STP: Cl2, C2H6, and Xe.
Which of the following statements are true regarding these gas samples?


True False  The Xe gas molecules collide with the container walls most frequently.

True False  The C2H6 gas sample has the largest average kinetic energy.

True False  The mass of the gas in each container is the same.

True False  The Xe gas sample has the lowest density.

True False  The Xe gas sample has the most molecules of gas present.

True False  Each Xe gas particle collision with the container wall is more forceful as compared to each C2H6 and Cl2 collision.
