CHEM 101 Lecture Notes - Lecture 2: Limiting Reagent, Molar Mass, Reagent
Document Summary
Refers to the maximum amount of a product. Assumes all of at least one reactant is used up. Note: on tests, always check to see if reaction equations are balanced. In most reactions, the actual yield is far less than the theoretical yield. % yield = (actual yield/theoretical yield) * 100. Both actual and theoretical yield can be in either grams, moles, or liters. This is because they"re the same compound. If they"re both in moles and you converted them each to grams, the molar mass conversion factors would be in the numerator and denominator of the % yield calculation and cancel out. The same holds if you wanted to convert from mass to volume. As a result, as long as actual and theoretical yield are in the same units, they can be in moles, grams, or even liters. So, mass, particle count, and volume are all valid units for percent.
