The theoretical yield is the maximum amount of product that can be produced in a reaction. The percent yield is equal to the actual yield divided by the theoretical yield times 100%. It also discusses percetnage purity which is how much of the pure substance is present in an impure sample. 00:00 Four kinds of percentage 01:28 Example 1 04:45 Example 2 09:18 Formulas 10:50 Example 3 15:05 Percentage by mass 16:32 Water of crystallization 17:50 Example 4 19:38 Empirical Formula 21:36 Do we round off? 22:26 Example 5 24:52 relation to Mr
