Web17 aug. 2024 · Atomic mass, also known as atomic weight is the mass of an individual atom expressed in atomic mass units (a.m.u). One a.m.u is the mass of an element relative to the 1/12 mass of a carbon atom. On the other hand, the molar mass is the mass of the one mole of particles ( atoms or molecules) expressed in grams per mole (g/mol). Web8 apr. 2024 · Molar Mass It is equal to the sum of the individual atomic mass of each substance (in grams) in the molecule. By adding the atomic weight of the constituent elements in grams we will get the molar mass equation as: Molar mass (AB2) = atomic mass (in grams) of A + 2 × atomic mass of B (in grams) Solved Examples
