Percent Solution ↔ Molarity Converter

Convert a percent weight/volume (%w/v) solution to molar concentration, or the reverse.

Molecular weight — MW (g/mol)

Percent solution (%w/v — g per 100 mL)

Fill in molecular weight and either Percent or Molarity — leave the other blank to solve for it.

Molarity (M, mol/L)

This calculator converts %w/v (grams of solute per 100 mL of solution) only. For %v/v or %w/w solutions, convert to %w/v first using the solute's density.
