Stoichiometry is based on the law of conservation of mass

Stoichiometry depends on the fact that matter is conserved in chemical processes, and calculations giving mass relationships are based on the concept of the mole. One mole of any element or compound contains the same number of atoms or molecules, respectively, as one mole of any other element or compound. the subject of this chapter and it is based on CHAPTER 9 Stoichiometry - Quia CHAPTER 9 DO NOT EDIT--Changes must be made through “File info” ... Reaction stoichiometry, the subject of this chapter, is based on chemical equations and the law of conservation of mass. All reaction stoichiometry calculations start with a Page 1/4

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. This means that if the amounts of the separate reactants are known, then the amount of the product can be calculated.

The Law of Conservation of Mass states that 'the mass of the universe is constant'. This means that mass is neither created nor destroyed. According to the Law of Conservation of Mass, one has to balance every chemical equation so that the mass of substances remain the same before and after the chemical change.
