7 FOCUSED TOOLS
Reaction quantities & yield calculators
Compare theoretical reaction quantities, actual yield and purity.
Choose the right calculation
Balance the chemical equation before using mole ratios. Identify the limiting reactant separately. Yield, purity and atom economy measure different aspects of a reaction and should not be substituted for one another.
Find a tool for your question
Percent Yield Calculator
Compare actual product yield with theoretical yield.
Theoretical Yield Calculator
Calculate theoretical product mass from reactant mass and a molar stoichiometric ratio.
Atom Economy Calculator
Find theoretical desired-product mass relative to reactant mass in a balanced equation.
Percent Purity Calculator
Calculate a sample’s pure-component mass as a percentage of total sample mass.
First Order Reaction Remaining Calculator
Estimate reactant concentration after a first-order reaction interval.
First Order Reaction Half Life Calculator
Find half-life from a first-order reaction rate constant.
Reaction Conversion Calculator
Find the consumed fraction of an initially supplied reactant.
Is percent yield the same as atom economy?
No. Yield compares actual product against a theoretical amount; atom economy describes stoichiometric use of reactant mass in the desired product.
