For hydrogen gas, calculate
Average velocity at STP.

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)`
Average velocity, `u_("avg")=((8RT)/(piM))^(1/2)=(((8)(8.314JK^(-1)mol^(-1))(273.15K))/((3.1416)(2.016xx 10^(-3)kg mol^(-1))))^(1/2)= 1.69xx 10^(3) ms^(-1)`.
