Question

Equal numbers of moles of Gas A and Gas B are in the same 2.0 L container at room temperature. Gas B has a molar mass that is twice as great as the molar mass of Gas A Which of the following statements is true? The molecules of Gas B have a greater average velocity than the molecules Gas A The molecules of Gas A have a greater average kinetic energy than the molecules of Gas B A. of B. C. Gas B has a greater partial pressure than Gas A D. The density of Gas A is greater than that of Gas B E. None of the above is true. opened and more gas is torm and the femperature is now 26 C How is

Explanation / Answer

B) the molecules of Gas A has greater average kinetic energy than the molecule of gas B

as the Molar mass of Gas B is more and the container at room temperature
