Chemistry Calculators

Browse chemistry calculators and related tools on Calculator 360.

Calculate molar or mass concentration, solute mass, amount, volume, conversion, mass fraction, or mass ppm.

Balance a molecular equation and optionally estimate a limiting reactant and theoretical yield from entered amounts.

Calculate mass density, mass, volume, or relative density with explicit units and a selectable reference density.

Calculate molar mass from a chemical formula, then convert between mass, moles, entities, or ideal gas volume.

Solve C1 × V1 = C2 × V2 for one unknown, and calculate the theoretical dilution factor and volume difference.

Estimate pH from H⁺ activity, ideal dilute concentrations, pOH, or an ideal buffer model, with each assumption stated.
