A closed vessel holds two gases X and Y. The molar mass of X is 4 times that of Y, and the masses of the two gases are equal. Which statements are correct?

Options:(select one or more)

Answer:

A, B, C

Solution:

Equal $T$ gives equal average energy (A).

$v_{Y} = 4 v_{X} = 2 v_{X}$ (B).

$\frac{n _{Y}}{n _{X}} = \frac{M _{X}}{M _{Y}} = 4$ , so $Y$ has 4 times the

molecules and 4 times the pressure (C). D is false. A, B and C.
