Molar Ratio

Molar ratio (pronunciation: /ˈmoʊ.lər ˈreɪ.ʃoʊ/) is a term used in Chemistry to denote the relationship between the amounts of substances involved in a chemical reaction. It is derived from the Latin word 'molaris', meaning 'mill-like', in reference to the grinding process of teeth, and the English word 'ratio', meaning 'relationship'.

Definition

The molar ratio can be defined as the ratio of the number of moles of one substance to the number of moles of another substance in a balanced chemical equation. It is a unitless quantity and is used to convert between the amounts of reactants and products in a chemical reaction.

Calculation

The molar ratio is calculated by dividing the number of moles of one substance by the number of moles of another substance. This ratio is often used in stoichiometry, the study of the quantitative relationships between the amounts of reactants used and products formed in a chemical reaction.
