About this calculator
Molarity (M) is moles of solute per liter of solution. A 1 M solution has 1 mole dissolved per liter. Calculations work in three directions: find M from amount and volume, find amount needed for a target M, or find volume for a given amount.
Frequently asked
Molarity uses volume of solution; molality uses mass of solvent. Molality is preferred for temperature-sensitive work because mass doesn't change with temperature.
