Molar mass is the mass of one mole of a substance, expressed in grams per mole (g/mol), calculated by summing the atomic masses of all atoms in a compound.

How do you calculate molar mass?

Molar mass is calculated by adding the atomic masses of each element in the chemical formula, multiplied by their respective quantities.

Why is molar mass important?

Molar mass is crucial for stoichiometry, solution preparation, chemical reactions, and quantitative chemical analysis.
