Density of air in mol/l
WebDensity is a measure of mass. The formula for density is d = m/v, where d is the density, m is the mass, and v is the volume. In this session, let us discuss the density of air, … In chemistry and related fields, the molar volume, symbol Vm, 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 metres per mole (m /mol), although it is more typical to use the units cubic decimetres per mole (dm /mol) for gases, and cubic centimetres per mole (cm /…
