Limiting Reagent: Which One Runs Out First?

Find the reactant that caps your yield, then compute theoretical and percent yield — stoichiometry made visual.

Limiting Reagent Calculator — CH₄ + O₂

Find the limiting reagent in CH₄ + O₂ (coefficients 1:2) from the moles of each reactant. The smaller mole-to-coefficient ratio limits the reaction.

Limiting Reagent Calculator — H₂ + O₂

Find the limiting reagent in H₂ + O₂ (coefficients 2:1) from the moles of each reactant. The smaller mole-to-coefficient ratio limits the reaction.

Limiting Reagent Calculator — N₂ + H₂

Find the limiting reagent in N₂ + H₂ (coefficients 1:3) from the moles of each reactant. The smaller mole-to-coefficient ratio limits the reaction.

Limiting Reagent Calculator — HCl + NaOH

Find the limiting reagent in HCl + NaOH (coefficients 1:1) from the moles of each reactant. The smaller mole-to-coefficient ratio limits the reaction.

Limiting Reagent Calculator — Al + Fe₂O₃

Find the limiting reagent in Al + Fe₂O₃ (coefficients 2:1) from the moles of each reactant. The smaller mole-to-coefficient ratio limits the reaction.

Limiting Reagent Calculator — AgNO₃ + NaCl

Find the limiting reagent in AgNO₃ + NaCl (coefficients 1:1) from the moles of each reactant. The smaller mole-to-coefficient ratio limits the reaction.

Percent Yield Calculator — reaction

Calculate the percent yield of a reaction from the actual and theoretical product amounts. % yield = actual ÷ theoretical × 100.

Percent Yield Calculator — aspirin synthesis

Calculate the percent yield of a aspirin synthesis from the actual and theoretical product amounts. % yield = actual ÷ theoretical × 100.
