how to find mass using percent yield. When you know the number of moles that you expect you will multiply by the molar mass of the product to find the theoretical yield in grams. But since the abundance is in you must also divide each abundance value by 100.

Cancel units and calculate. For a chemical reaction which goes to completion 1. You determine percent yield of a chemical reaction with the following formula.
Calculate moles using our mole calculator.
The actual mass obtained is 1212 g. Be sure that actual and theoretical yields are both in the same units so that units cancel in the calculation. The mass of oxygen gas must be less than the 400. Thus Atomic mass of oxygen 15995 amu 9976100 16999 amu 04100 17999 amu 2100 15956612 amu 00067996 amu 0035998 amu.
