No atoms can be created during a chemical reaction, so the mass of the reactants will equal the mass of the product. You will have the same number and types of atoms on both sides of the reaction. This means no mass is lost or gained so we say mass is conserved during a reaction.

Relative Formula Mass

The relative formula mass is the sum of all the relative atomic masses (Ar) of the atoms in the formula added together. For example: HCl. This contains 1 atom of hydrogen (H) and 1 atom of chlorine (Cl).

Concentration of Solutions

Concentration is the amount of a substance in a specific volume of a solution. The more substance that is dissolved, then the more concentrated the solution is.
