Why do we use moles in chemistry and what is the significance of this unit of measurement in chemical reactions and calculations?
We use moles in chemistry because it provides a convenient way to count and compare large numbers of atoms or molecules. One mole is defined as the amount of substance that contains the same number of entities as there are atoms in 12 grams of carbon-12, which is Avogadro's number (6.022 x 10^23). This allows us to easily convert between the mass of a substance and the number of atoms or molecules it contains, facilitating stoichiometry calculations in chemical reactions. Moles are crucial in determining the ratios of reactants and products in a chemical reaction, as well as in calculating the amounts of substances needed or produced.
