A successful champion must also master quantitative skills. This involves calculating molar mass , determining stoichiometric ratios in reactions, and understanding oxidation-reduction (redox) processes . These are not just mathematical exercises; they are the tools used to manufacture life-saving medicines and high-strength alloys. determining stoichiometric ratios in reactions
