Why do we use moles in chemistry and what is their significance in chemical calculations?
Moles are used in chemistry to measure the amount of substance in a sample. They are significant in chemical calculations because they allow us to easily convert between the mass of a substance and the number of atoms or molecules it contains. This helps chemists accurately determine the quantities of reactants and products in chemical reactions.
