Definition of Mole Ratio



The compounds are formed as a result of chemical reactions when they react in a defined ratio. If the ratio is not balanced, then the reactants would be leftover. The mole ratio is a term that is defined as the ratio, in moles, between the quantities of the compounds that are participating in a chemical reaction.

 


The mole ratios are employed in many problems of chemistry as a conversion factor between the reactants and the products. The mole ratio is also named as mole-to-mole ratio and it is determined by inspecting the coefficients in a balanced chemical equation.

 


Example of Mole Ratio:

2 H2(g) + O2(g) → 2 H2O(g)

Consider the reaction between oxygen and hydrogen which results in the formation of a molecule of water. When one mole of oxygen is used, two moles of water are formed. And if two moles of hydrogen are used, two moles of water are formed.
