The mass concept measures the quantity of matter existing in an object. It is a quantitative property of an object against the acceleration. The mass and weight of an object are not the same. The molar mass (M) is a physical property and it is defined as the mass of one mole of the chemical substance or it is a ratio of the mass of a chemical compound to its amount of chemical substance. The unit of molar mass is kg\/mol.<\/p>\n\n\n\n
