Molarity calculator

Calculate molar concentration from mass, MW and volume — or back-calculate the required mass

Input parameters

e.g. NaCl = 58.44, Glucose = 180.16

Results

Enter mass, MW and volume, then click "Calculate concentration"

Formulas

C = m / (MW × V)

C: molar concentration (mol/L) | m: solute mass (g) | MW: molecular weight (g/mol) | V: volume (L)

m = C × MW × V

Back-calculate required mass from target concentration
