About Limiting Reagent Calculator — RMgX + carbonyl
Find the limiting reagent in RMgX + carbonyl (coefficients 1:1) from the moles of each reactant. The smaller mole-to-coefficient ratio limits the reaction. The calculation uses compare (moles ÷ coefficient). Why this calculation counts: Molar mass, limiting reagent and yield are the backbone of quantitative chemistry. A miscounted subscript or the wrong limiting reactant throws off every downstream amount. Reaction RMgX + carbonyl: stoichiometric coefficients RMgX=1, carbonyl=1. Common pitfalls to avoid: assuming the reactant you have less of (by mass) is limiting; forgetting to balance the equation first; mixing up actual and theoretical yield. All maths runs locally in your browser; no data is ever sent to a server. That privacy is exactly why researchers link these calculators from protocols, theses and standard operating procedures.
