For hydrogen gas, calculate most probable velocity at `0^(@)C`

Text Solution

Verified by Experts

Given : Molar mass, `M" of "H_(2)= 2.01g mol^(-1)= 2.016 xx 10^(-3) kg mol^(-1), J= kgm^(2)s^(-2)`
Most probable velocity, `u_("mp")=((2RT)/(M))^(1/2)=(((2)(8.314JK^(-1)mol^(-1))(273.15K))/(2.016xx 10^(-3)kg mol^(-1)))^(1/2)= 1.50 xx 10^(3) ms^(-1)`.
