Chemistry Tools

Molar mass, molarity, equation balancing and reaction prediction.

• Chemical Equation Balancer — Balance chemical equations exactly, including brackets, hydrates and ionic charges, with an atom-by-atom check of the result.
• Periodic Table Reaction Predictor — Pick elements or compounds and get a rule-based prediction of common school-level reactions, balanced automatically with an explanation.
• Molarity Calculator — Solve for molarity, moles, mass or volume of a solution from a formula or molar mass, plus a C1V1 = C2V2 dilution solver.
• Molecular Weight Calculator — Calculate the molar mass of any chemical formula with a per-element breakdown of atom counts, mass contribution and mass percent.
