/ˌstɔɪ.kiˈɒm.ə.tri/ IELTSAcademic
noun
Stoichiometry is the part of chemistry that studies the amounts of substances in a reaction. It helps you work out how much reactant you need and how much product will form.
- We used stoichiometry to balance the reaction.
- Stoichiometry helps predict the product amount.
- The teacher explained stoichiometry clearly.
Adinary Nuance
Stoichiometry is not just 'chemistry' in general. It is the measuring part of chemistry, where you calculate exact amounts in a reaction. Use it when you mean numerical relationships, not when you mean a chemical process overall. It is more specific than 'chemical equations' and more technical than 'measurement.'
