Stoichiometry and reactions

First steps in quantitative chemistry — balancing equations, mole ratios, and yield.

Core skills

• Balancing chemical equations
• Mole-to-mole and mass-to-mass stoichiometry
• Limiting reactants and percent yield
• Solution stoichiometry and molarity

Practice focus

Work through mole-map problems systematically: given → wanted, unit conversion factors, and check with limiting reagent when two reactants are present.

Tutoring tie-in

Included subscription hours can cover problem-solving strategy for multi-step stoichiometry and exam-style mixed problems.
