Kinetic energy

Molar mass of a gas is 4 grams. At certain temperature, kinetic energy per mole of the gas is 0.2×1011 ergs. At the same temperature, RMS velocity of the gas would be 


K.E/mole = 32RT

2 ×K.E/mole = 3 RT

RMS velocity, C = 3RTM

RMS velocity, C=2×K.E/moleM

RMS velocity, C = 2×2×10104

RMS velocity, C = 105cm/s
