Stoichiometry is a fundamental topic in chemistry that deals with the quantitative relationships between reactants and products in chemical reactions, making it extremely important for MDCAT, ECAT, NUST and FSC board exams. It includes concepts such as the mole, molar mass, Avogadro’s number, limiting reagent, percentage yield, and empirical and molecular formulas, which help students calculate the exact amounts of substances involved in reactions. A strong command of stoichiometry enables aspirants to solve numerical problems quickly and accurately in entry tests. At PLS Academy, stoichiometry is taught through step-by-step methods, shortcuts for MCQs, and extensive practice to help students achieve high scores in Entry tests and board examinations.
