Percentage yield is calculated as the percentage of the that is actually made. Percentage yield might decrease because some of the reactants either or react to form other products.
is a way of comparing reactions to see which utilises the most . It is better for this to be higher because it is more economic and .
When a substance is dissolved in a solvent, a is formed. Its concentration can be calculated by dividing the number of moles of solute by its total . This concentration has units of . If more moles are dissolved, or a smaller volume of is used, then the concentration will be higher. In a titration, one solution with a concentration is reacted with a solution of unknown concentration to find its concentration.
One mole of always takes up the same volume, which is dm³, at room temperature and .
