Two Types Of Yield

• Theoretical Yield

• Actual Yield

Theoretical Yield

• This is the maximum amount of product you could get after a reaction

Actual Yield

• The actual amount of of product you get after a reaction

Percentage Yield

• The purpose of calculating percentage yield is to know the efficiency of product after reaction

• Percentage Of Yield = Actual Yield / Theoretical Yield

Purity

• Purity is the measure of how much of your product is actually the real thing or pure

• Example - You isolate 10 grams of a white powder. lab analysis tells you only 7 grams is the actual product, the rest is just trash.

Percentage Purity

• Purity = Mass of pure product / Mass of impure product

Percentage Composition

• The percentage of composition is the mass of each element in a compound
