Calculators for stoichiometry and the mole concept: find the molar mass of any compound, convert between grams, moles, particles and gas volume at STP, and work out the percent yield of a reaction.

Type a chemical formula such as H2SO4, Ca(OH)2 or CuSO4·5H2O to get its molar mass in g/mol and the percent composition of each element. Optionally convert grams to moles.

Grams ↔ Moles

Convert grams to moles and moles to grams with n = m ÷ M, and get the number of particles with Avogadro's number and the volume of a gas at STP.

Calculate the percentage yield of a reaction from the actual yield and the theoretical yield: % yield = actual ÷ theoretical × 100.
