## Density of a Gas PV = CoRT/M PM = CoRT/V PM = dRT/V Therefore d = PM/RT which is the density of a gas Density of a gas = PM/RT Density of a gas is maximum at high P and low T. Vapour density (unit less) This is the ratio of the density of a gas at some T & P to the density of the He gas at the sa...

## Density of a Gas PV = CoRT/M PM = CoRT/V PM = dRT/V Therefore d = PM/RT which is the density of a gas Density of a gas = PM/RT Density of a gas is maximum at high P and low T. Vapour density (unit less) This is the ratio of the density of a gas at some T & P to the density of the He gas at the same T & P [V.] of gas = g  = PM/RT = M'/MH2 [V.D.] = M'/2 (Hydrogen with respect to the density of He gas may be 2, but if the gas is changed, it will be 32)
