how to find percent yield when given grams. Using the theoretical yield equation helps you in finding the theoretical yield from the mole of the limiting reagent assuming 100 efficiency. 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.

How do we find the percentage here. The percent yield equation is given below. The reaction only goes to 882 completion because this is the actual yield you get therefore 882 of the theoretical yield will the the mass of product you get from your reaction.
Given the reaction Na 2 Saq 2 AgNO 3 aq Ag 2 Ss 2 NaNO 3 aq How many grams of Ag 2 S will form when 394 g of AgNO 3 and an excess of Na 2 S are reacted together.
Its going to be 04 moles over 05 moles times 100 and we have 80. The calculated or expected amount of product is called the theoretical yield. The percent yield is simply the actual yield divided by theoretical yield multiplied by 100. A percent yield of 90 means the reaction was 90 efficient and 10 of the materials were wasted they failed to react or their products were not captured.
