Chemistry & Material Science Calculators
Molarity, titration, stoichiometry, thermodynamics, material stress, polymer density, and metallurgy.
The chemistry and materials calculators handle molarity, dilution, pH, density, gas laws and related quantities. Each tool states its formula and units, and SI units are used throughout unless noted.
Laboratory results depend on temperature, purity and measurement accuracy. Use these calculators for preparation and checking, and follow your lab's safety procedures when handling chemicals.
Molarity Calculator
Calculate the molar concentration of a solution from solute mass, molar mass and solution volume.
Dilution Calculator (C₁V₁ = C₂V₂)
Work out how much stock solution and solvent you need to make a diluted solution.
pH Calculator
Convert between pH, pOH, [H⁺] and [OH⁻] for aqueous solutions at 25 °C.
Molar Mass from Formula
Calculate the molar mass of any chemical compound from elemental atomic masses and atom counts.
