Chemistry calculators
Solve chemistry on the spot: molarity, solution dilution and pH. TudoCalc's chemistry calculators show the formula and are handy in the lab and for exams.
Molarity
Calculate the molarity of a solution from solute mass, molar mass and volume.
Solution dilution
Find the final volume and how much water to add to dilute a solution to the target concentration.
pH and pOH
Calculate pH, pOH and the OH⁻ concentration from the H⁺ ion concentration.
Molar mass
Calculate the molar mass of a chemical formula, like H2O, C6H12O6 or Ca(OH)2, in g/mol.
Moles and grams
Convert between moles and grams using the molar mass, and see the number of particles.
