How to use the Molarity Calculator

  1. Pick what to solve for: Molarity, Mass or Volume.
  2. Enter the known values plus the compound's molecular weight (use our Molecular Weight Calculator).
  3. Read the result. For dilutions, apply M₁V₁ = M₂V₂.

Molarity in the lab

M = moles / liters. 1 M NaCl = 58.44 g/L (1 mol of NaCl dissolved in 1 L).

Dilution: to make 100 mL of 0.1 M from 1 M stock, use 10 mL stock + 90 mL solvent.
