Question

for a gas the largest fraction of molecules a velocity of 4.1 x 10⁴ Cm S¹ at 288k. calculate the molecular mass of the gas. (given: R=8.34x10⁷ ergs k¹ mol¹)​

Answer 1

Answer:

Answer

Correct option is

A

M

2RT

Distribution of fraction of molecules with velocity.

Here, x is the position of most probable velocity.

most probable velocity, V

mp

=

M

2RT

, where T=Absolute temperature

M=Molar mass of gas.
