Molecular weight is the weights of the atoms in the molecule. â¢ Molecular weight gives the average mass of the molecule (mass of Avogadro number of molecules), whereas atomic mass gives the mass of a single atom (without considering the average mass of the other isotopes).

V. Mass and Weight. [NOTE 1, See page 6] The mass of an object is a measure of the objectâs inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s 2. In trade and commerce and everyday use, the term weight is often used as a synonym for mass..
