Answer:
Molecular Mass and Mole Concept
This concept can be extended to calculate molecular masses. The molecular mass of a substance is the sum of the atomic masses of all the atoms in a molecule of the substance. It is therefore the relative mass of a molecule expressed in atomic mass units

Hope this helps you
Answer:
The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol). The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms.Molecular weight is the mass of one molecule of a compound, while molar mass is the mass of one mole of a compound.The sum of the atomic masses of all atoms in a molecule, based on a scale in which the atomic masses of hydrogen, carbon, nitrogen, and oxygen are 1, 12, 14, and 16, respectively. For example, the molecular weight of water, which has two atoms of hydrogen and one atom of oxygen, is 18 (i.e., 2 + 16).Converting Grams to Moles
For a single element, the molar mass is equivalent to its atomic weight multiplied by the molar mass constant (1 g/mol).
For a compound, the molar mass is the sum of the atomic weights of each element in the compound multiplied by the molar mass constant.
