In chemistry, the molar mass M is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance.[1] The base SI unit for molar mass is kg/mol. ......However, for historical reasons, molar masses are almost always expressed in g/mol.Vapor pressure lowering is a colligative property of solutions. The vapor pressureof a pure solvent is greater than the vapor pressure of a solution containing a non volatile liquid. This lowered vapor pressureleads to boiling point elevation.
