Molecular Weight Calculator — Frequently Asked Questions
Q1 What is the difference between molecular weight and molar mass? ▾
Molecular weight is dimensionless (relative to 1/12 the mass of Carbon-12) or given in Daltons (Da). Molar mass has physical units of grams per mole (g/mol), but both share the same numerical value.
