Find the rms speed of the molecules of a sample of n2 (diatomic nitrogen) gas at a temperature of 34.3°c.

Root mean speed (rms) is the measure of the speed of the particle in a gas. it is square root of the velocity squared of the molecules in a gas.

that is rms = square root of (3RT/M)

R = gas constant (8.314)

T=temperature

M=mass (0.028kg)

rms is therefore square root of [ 3x 8.314 x (34.3+273) ] / 0.028kg

rms = 523.20m/s
