- Law of conservation of mass Total mass of reactants before reaction is equal to total mass of products after the reaction. Stoichiometry In the late 1700's, a French noble man named Antoine Lavoisier observed that the total mass of all substances present after a chemical reaction is same as total mass before the reaction.
- d) Use mathematics and computational thinking to identify and solve different types of reaction stoichiometry problems (i.e., mass to moles, mass to mass, moles to moles, and percent yield) using significant figures. e) Plan and carry out an investigation to demonstrate the conceptual principle of limiting reactants.
- Stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the total mass of the products, leading to the insight that the relations among quantities of reactants and products typically form a ratio of positive integers.
