Stoichiometry is a section of chemistry that involves using relationships between reactants and/or products in a chemical reaction to determine desired quantitative data. In Greek, stoikhein means element and metron means measure, so stoichiometry literally translated means the measure of elements.

Stoichiometry is the study of the relative quantities of reactants and products in chemical reactions and how to calculate those quantities. Chemical equations are symbolic representations of chemical reactions. The reacting materials (reactants) are given on the left, and the products are displayed on the right, usually separated by an arrow showi...
Molar ratios, or conversion factors, identify the number of moles of each reactant needed to form a certain number of moles of each product. Chemical equations are symbolic representations of chemical reactions. In a chemical equation, the reacting materials are written on the left, and the products are written on the right; the two sides are usual...
Mole-to-mole conversions can be facilitated by using conversion factors found in the balanced equation for the reaction of interest.
Mass-to-mass conversions cannot be done directly; instead, mole values must serve as intermediaries in these conversions. A chemical equation is a visual representation of a chemical reaction. A typical chemical equation follows the form aA+bB→cC+dDaA+bB→cC+dD where an arrow separates the reactants on the left and the products on the right. The coe...
Mass-to-mole conversions can be facilitated by employing the molar mass as a conversion ratio. The mole is the universal measurement of quantity in chemistry. However, the measurements that researchers take every day provide answers not in moles but in more physically concrete units, such as grams or milliliters. Therefore, scientists need some way...
The reagent that limits how much product is produced (the reactant that runs out first) is known as the limiting reagent. In a chemical reaction, the limiting reagent, or limiting reactant, is the substance that has been completely consumed when the chemical reaction is complete. The amount of product produced by the reaction is limited by this rea...
The percent yield of a reaction measures the reaction’s efficiency. It is the ratio between the actual yield and the theoretical yield. In chemistry, it is often important to know how efficient a reaction is. This is because when a reaction is carried out, the reactants may not always be present in the proportions written in the balanced equation. ...
