Chemical Calculations
Learning Time: 5-15 hours
Content: Chemical calculations are a subject that provides quantitative analysis of chemical reactions and calculating the amounts of substances. This area covers mole-stoichiometry, mass-molecule relationships, reaction efficiency, titration calculations, applications of gas laws, and concentration analysis. TYT focuses on mole and mass calculations, while AYT focuses on complex reaction efficiency and titration analysis. The current 2025 curriculum also covers chemical measurement techniques in environmental analysis. Learning this topic provides a critical skill for laboratory work and industrial processes.
