Reactions & Yield

Stoichiometry, limiting reactants, yield and empirical formulas.

• Atom Economy Calculator Atom economy of a reaction from the molar masses and coefficients in its balanced equation.
• Empirical and Molecular Formula Calculator Empirical formula from percent composition or masses, and the molecular formula from the molar mass.
• Limiting Reactant Calculator Which reactant runs out first, the product it allows and how much of the other is left over.
• Stoichiometry Calculator Mass and moles of one substance from another, using the coefficients of a balanced equation.
• Theoretical and Percent Yield Calculator Theoretical yield from the limiting reactant, and percent yield from what you actually collected.
