TOOL
Balance any chemical equation by entering reactants and products, then feed the result straight into the stoichiometry calculator to get moles, mass, or number of particles — with limiting reagent support.
This tool combines two steps common to almost every chemistry problem: first it balances the equation so it satisfies the law of conservation of mass, then it lets you calculate amounts of reactants and products from the already-balanced coefficients.
Enter reactants and products without coefficients; the app finds the smallest integer coefficients that balance the equation.
Convert between moles, grams, and number of particles (atoms or molecules) using the molar mass of each species.
Enter the starting amount of each reactant and the app identifies which one runs out first and how much product forms.
Calculate the theoretical amount of product from the available reactants.
