We can use that relation to answer stoichiometry questions in terms of the masses of a particular substance, in addition to moles. We do this using the following sequence: moles of A molar → ratio moles of B molar → mass grams of B. Collectively, these conversions are called mole-to-mass calculations.

Input the chemical equation, and the calculator will instantly determine the number of reactants and products involved. This stoichiometry calculator lets you calculate the relative amounts of reactants and products involved in a chemical reaction.

2022年9月21日 · Mass-mass calculations involve converting the mass of a reactant to moles of reactant, then using mole ratios to determine moles of product which can then be converted to mass of product. If matter is neither created nor destroyed, why can’t we just go directly from grams of reactant to grams of product?

Convert the mass of one substance (substance A) to the corresponding number of moles using its molar mass. From the balanced chemical equation, obtain the number of moles of another substance (B) from the number of moles of substance A using the appropriate mole ratio (the ratio of their coefficients).

Our solutions demonstrate how to use the factor label method (conversion factors) with an understanding of mole ratios and molar mass to solve for the unknown. The problems on this page are three-step problems.

This online Stoichiometry Calculator finds the stoichiometric coefficients to balance a given chemical equation and computes amounts of the reactants and products of the reaction, both in moles and grams.

2023年7月30日 · To solve mass stoichiometry, follow these steps: (1) Write the balanced chemical equation, (2) Convert the given mass of the reactant to moles, (3) Use the stoichiometric ratios from the balanced equation to convert moles of the reactant to moles of the product, (4) Convert moles of the product to mass.

2023年11月21日 · How do you convert mass to mass in stoichiometry? To convert from mass of substance A to mass of substance B in a chemical equation, first convert the mass of substance A, to...

To convert between moles and grams, multiply moles by the molar mass to get grams, or divide grams by the molar mass to get moles. For example, lets say we have 100g of MgCl2 and want to convert it to the number of moles: 100/95.211 = 1.05 moles.
