Stoichiometry Calculator
Convert moles and mass between reactants and products using reaction coefficients.
Use this tool when you need a quick stoichiometry calculation without writing out the entire ratio by hand. It uses known moles, the known coefficient and the target coefficient to estimate target moles and mass.
It is useful for exercises, revision and checking answers in basic and general chemistry.
Use clear inputs to get a more useful result.
