Question

calculate rms velocity of the molecules of hydrogen at NTP ...given density of hydrogen at NTP is 0.0899 kg per metre cube

Answer 1

At S.T.P. Pressure is = 10^5 N/m^2

 Given density of gas = 0.0899 kg/m^3

, We know that r.m.s velocity of gas is given by

Vrms = √(3p/ρ) = √[(3 x 10^5)/0.0899] = 18.2675 x 10^2 = 1826.75 m/s
