Molarity calculator

Solve for mass, volume, molarity, or molecular weight — enter any three; leave one blank. Uses C = m / (MW × V) with consistent SI conversions.

Mass

Molecular weight

Volume

Molarity

Enter three positive numbers; leave the fourth field empty. The answer appears in that field and below. MW is assumed in g/mol (numerically equal to Da per mole for practical use).
