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. BY . Dr. . Alka. N . Choudhary. Associate Professor. Division of Pharmaceutical Sciences. S.G.R.R.I.T.S., Paten Nagar, Dehradun (UK). “. Chemistry has an important role to play in achieving a sustainable civilization on earth.”. 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 .
