Step-by-Step Mass to Mole. What is Stoichiometry. Stoichiometry is the study of the relationships or ratios between two or more substances undergoing a physical or chemical change. We will be taking steps to solve the different equations. It’s a process that allows us to mathematically convert and calculate the relationships between the amount of reactants and products in a chemical reaction.. Graphical representation .
