WebThe average kinetic energy for a mole of particles, KE avg, is then equal to: KE avg = 1 2 M u rms 2. where M is the molar mass expressed in units of kg/mol. The KE avg of a mole of gas molecules is also directly proportional to the temperature of the gas and may be described by the equation: KE avg = 3 2 R T. WebMolar volume. In chemistry and related fields, the molar volume, symbol Vm, [1] or of a substance is the ratio of the volume occupied by a substance to the amount of substance, usually given at a given temperature and pressure. It is equal to the molar mass ( M) divided by the mass density ( ρ ): The molar volume has the SI unit of cubic ...
