WebPercentage composition of a compound is a ratio of an amount of each element to the total amount of individual elements in a compound, which is then multiplied with 100. Let us take an example of H 2 O i.e. Water. Water has 2 molecules of hydrogen, and one mole of water is of 18.0152 grams. And one mole of a hydrogen atom is of 1.008 grams. WebStoichiometry. Stoichiometry is the quantitative relationship between the amount of reactants used and the amount of products formed. It is based on the law of conservation of mass. The law states that matter is neither created nor destroyed in a chemical reaction. Meaning that the mass of the reactants MUST equal the mass of the products.
