Carbons molar mass is 12 gmol and oxygens is 16 gmol so the total is 12 16 16 44. 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. 100 yield of Li3N 02882 moles.
The Percentage yield is determined by divide the actual yield with the theoretical yield and multiplied by 100.
Actual yield is the amount of product you actually got while theoretical is the maximum possible yield. Percentage Yield Actual YieldTheoretical Yield x 100. Actual yield is the amount of product you actually got while theoretical is the maximum possible yield. How many grams with a percent yield How many grams of FeOH2 were isolated from the reaction of 850 mL of a 0360 M NaOH solution with excess FeClO32 if the reaction occurred with an 869 yield.
