4. The concentration of a solution is given by the amount of a solute dissolved in a unit volume of the solution.
5. Molar concentration is the concentration of a solution expressed in mol/dm³.
6. The theoretical yield is the calculated amount of products that would be obtained if the reaction is completed.
