You may have used too much of the reactants. You may have recorded the mass of the reactants or products incorrectly.
if you received 85.0 percent back from your product then your percent yield is 85 percent.
why don't reactions give us a 100 percent yield?
The yield would be 15.38%.
that means that 69.8 grams will be produced when the theoretical yield is 100 grams.
The reaction may have not been complete yet, therefore resulting in a higher percent yield than 100%
Impurities in the substance can cause a greater percent yield. I recommend redoing the lab for better results.
the amount of product obtained over the amount possible multiplied by 100
Percent yield = (actual yield/expected yield) x 100
Theoretically hundred procent yield wouldn't be possible. Perhaps you did something wrong in your calculation? However: some other side-reaction may have taken place where acetanilide was also formed and therefore giving you a yield over hundred procent.
The percent yield is the ratio of the actual yield to the theoretical yield. A mole ratio is a conversion factor derived from the coefficient of a balanced chemical equation interpreted in terms of moles.
calculating the percent yield.
if you received 85.0 percent back from your product then your percent yield is 85 percent.
If this is the actual yield, real amount produced, then you need the theoretical yield to find the percent yield. % yield = (actual yield / theoretical yield) x 100
Caco3 -------- CaO plus CO2 what is the theoretical yield of cao if 24 point 8 g of caco3 were heated what is the percent yield if one was able to obtain 13 point 1 g of CaO in the above proces?
Percent yield = Actual Yield / Theoretical Yield * 100 hope that helps :)
Do you need it? Are you being told to calculate it? percent yield = (actual yield) divided by (theoretical yield) x 100
Theoretical yield is how much product it is possible to obtain, based on a chemical equation. The actual yield is how much product you ACTUALLY obtain from an experiment. Comparing them is important because they can point you toward improving your technique to maximize your yield (which is the usually something to strive for), and it can give you a maximum yield you can expect for a particular experimental technique.
