Given:
m=molar mass of Nitrogen=28 gm./mol =2.8 x 10 ⁻² kg/mol
Temperature=T=273 +27 =300K
R=gas constant=8.314 joules/.mol K
To calculate RMS speed :
Formula:
μ=√3RT/M
=√(3*8.314*300)/(2.8x10⁻²)
=√267235.7
=516.9m/s
∴RMS of Nitrigen gas at 27 °c is 516.9m/s
m=molar mass of Nitrogen=28 gm./mol =2.8 x 10 ⁻² kg/mol

We have R.M.S
μ = in this M = Molar mass
And in the case of Nitrogen gas, T = 27 + 273 = 300 K.R = 8.314 (kg / )/ K mol
Since molar mass of Nitrogen gas = 28 gm/mol = 2.8 x kg/mol
Hence μ = = [ 3 x 8.314 x 300 / 2.8 x ] = [267235.7 = 516.9m/s
So the r.m speed for oxygen gas at 0°C (273K) = 516.9 m/s
μ = in this M = Molar mass
And in the case of Nitrogen gas, T = 27 + 273 = 300 K.R = 8.314 (kg / )/ K mol

Hence μ = = [ 3 x 8.314 x 300 / 2.8 x ] = [267235.7 = 516.9m/s
So the r.m speed for oxygen gas at 0°C (273K) = 516.9 m/s
