23.79 L/mol is the molar volume of ch4 gas under the conditions of temperature and pressure where its density is 0.674 g/l
molar mass of CH4= 16.04g/ ml
density of CH4 = 0.674 g/l
so molar volume of CH4= molar mass/ density
molar volume of CH4= 23.79L/mol
A substance's (chemical element or chemical compound) molar volume, denoted by the symbol Vm, is the volume occupied by one mole of that material at a specific temperature and pressure. It is determined by dividing the molar mass (M) by the mass density (). The definition of standard temperature and pressure (STP) is 0oC (273.15K) and 1atm pressure. The volume of one mole of a gas at STP is known as the molar volume of a gas.
