stoichiometry - the calculations of quantities in a chemical reaction mole ratio - a conversion factor derived from the coefficients of a balanced chemical equation interpreted in terms of moles mass-mass calculations - a stoichiometric computation in which the mass of products is determined from the given mass of reactants mole - quantity of matter that contains 6.02 x 10^23 particles of that substance reactant - A chemical substance that is present at the start of a chemical reaction ...

stoichiometry - The study of quantitative relationships between the amounts of reactants used and products formed by chemical reaction; is based on the law of conservation of mass. mole ratio - Ratio between the numbers of moles of any two of the substances in a balanced chemical equation. unknown - a variable whose values are solutions of an equation coefficient - a whole number that appears in front of a formula in a chemical equation balanced equation - a chemical equation in which mass...
