yeah tis the actual no of moles you get/theoretical no of moles *100

but isn't tht percentage yield? or is percentage yield and percentage purity the same thing?

this thread is a couple of years old :tongue:

percentage purity = (pure mass/impure mass) x 100

How do you know which is the pure and impure mass in an equation?

how do you know which is the pure and impure mass in the reaction?
