Two gases X and Y have their most probable speeds in the ratio 2 : 5 at a certain temperature. The ratio of their molar masses $M_{x} : M_{y}$ is -

Answer:

Solution:

At the same T, $u_{m p} \propto 1/ M$ .

$u_{x} / u_{y} = M_{y} / M_{x} = 2/5$ , so $M_{y} / M_{x} = 4/25$ .

$M_{x} : M_{y} = 25 : 4$ .

Answer: (D).
