Which one of the following statements about these systems is correct? A. The compressed N2 gas has a higher density than the compressed H2 gas. B. Both cylinders contain approximately the same number of molecules. C. Molecules of H2 move faster on average than molecules of N2. D. The pressure of the N2 gas is higher than the pressure of the H2 gas. E. None of the other statements is correct.
