### What is Meant by Molecular Weight?

In Chemistry, molecular weight is used to calculate stoichiometry in the chemical reaction. The molecular weight is also called the relative molecular mass. The molecular weight is defined as the sum of the atomic weight of the atom in a molecule. It is the mass of a molecule.
