A closed vessel holds a mixture of two monatomic gases X and Y. The molar mass of X is 9 times that of Y, and the mass of X is 3 times the mass of Y. Which statements are correct?

Options:(select one or more)

Answer:

A, B, C

Solution:

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

$v \propto \frac{1}{M}$ gives $v_{Y} = 3 v_{X}$ (B).

$\frac{n _{X}}{n _{Y}} = \frac{3}{9} = \frac{1}{3}$ , so $Y$ has 3 times

the molecules and 3 times the partial pressure (C), and D is false. A, B

and C.
