Stoichiometry & Dosage Calculation Stoichiometry ● Stoichiometry is the use of quantitative relationships between substances that are involved in chemical reactions which determine the amounts of the reactants or the products (Bauer, Birk, & Marks, 2019). Stoichiometry - the process of determining the amounts of substances in a chemical reaction (Bauer, Birk, & Marks, 2019). ● It is used to relate the reactants and products by using calculations and balanced equations (Bauer, Birk, & Marks, 2019). ● By knowing the amount of a reactant or a product, it is easier to determine the amount of another reactant or product in the same reaction and balance the equation (Bauer, Birk, & Marks, 2019). Stoichiometry ● Stoichiometry calculations deal with the mass or volumes of products and reactants. ● To solve stoichiometry problems it is important to master balancing equations, converting between grams and moles, calculating molar mass, and calculating mole ratios. ● Stoichiometry is the study of mass relations, where one or more substances undergo a physical change or a chemical change. ● After doing the calculations and conversions the equation must be balanced. ● After the equation is balanced, it is important to determine the mole relationship between the reactants and products in the chemical equation (Bauer, Birk, & Marks, 2019). Stoichimetry Tutorial Balancing Equations ● Steps to balancing Stoichiometry: ○ Identify each element in the equation. The number of atoms for each element must be the same on each side to be balanced. ○ The net charge must be the same on each side of the equation. ○ Start with the elements in one compound and change the number of the coefficient until the atoms are equal on each side. ○ Once you balance one element, then you
