Reacting masses a level chemistry
WebSummary of Reaction Masses and Atom Economy When a reaction occurs, we usually assume that the yield of the reaction is 100%. But this is not true in reality since the actual percent yield (or experimental yield) of a reaction is lower than the theoretical value.
