Calculate molar mass from atomic masses and the count of each element present.
Molar mass is the sum of every atomic mass in the formula. The defaults reproduce glucose at 180.16 g/mol, a useful check on the arithmetic. Molar mass is required for every conversion between the mass you can weigh and the moles a reaction actually consumes.
Molar Mass
M = Σ (atomic mass × number of atoms)
M = Σ (atomic mass × number of atoms) Molar mass is the sum of every atomic mass in the formula. The defaults reproduce glucose at 180.16 g/mol, a useful check on the arithmetic.
Molar mass is required for every conversion between the mass you can weigh and the moles a reaction actually consumes.
This calculator takes 6 inputs: Atomic mass of element 1, Atoms of element 1, Atomic mass of element 2, Atoms of element 2, Atomic mass of element 3, Atoms of element 3. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
