Which one do you need?
- Chemical Equation Balancer
- Type an unbalanced equation and get the smallest whole-number coefficients, with an element-by-element balance check. Handles combustion and redox equations.
- Stoichiometry Calculator (Mole Ratio)
- Convert a known mass or amount of one species into any other in a balanced equation. Shows the mole ratio, the moles, and the mass of the target species.
- Limiting Reagent Calculator
- Find which reactant runs out first, how much excess is left over, and how much product forms. Enter two reactants with coefficients and masses or moles.
- Theoretical Yield Calculator
- Compute the maximum mass of product obtainable from your limiting reactant, with the mole ratio, a purity correction and the yield per gram of reactant.
- Percent Yield Calculator
- Divide actual yield by theoretical yield to get percent yield, plus the mass lost, the loss as a percentage, and the moles behind both figures.
