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.
Percent yield is calculated by dividing the actual yield (the amount of product obtained in a chemical reaction) by the theoretical yield (the amount of product that should be obtained according to stoichiometry) and multiplying by 100 to get a percentage. This formula allows you to determine how efficiently a reaction was carried out by comparing the actual yield to the maximum possible yield.
the amount of product obtained over the amount possible multiplied by 100
Actual
The process you are describing is known as calculating the percent yield. It is a measure of how efficient a chemical reaction is by comparing the actual amount of product obtained (actual yield) with the maximum possible amount that could be obtained (theoretical yield) under ideal conditions.
Percent Yield.
if you received 85.0 percent back from your product then your percent yield is 85 percent.
To calculate percent yield, you would use the formula: (actual yield / theoretical yield) * 100%. If the actual yield is 14.4 and the theoretical yield is not provided, the percent yield cannot be calculated accurately without the theoretical yield.
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
Percent yield greater than 100% can occur due to impurities in the final product, incomplete reactions, or errors in the measurements taken during the experiment. It is a sign that not all of the reactants were converted to the desired product, leading to a higher yield than theoretically expected.
Do you need it? Are you being told to calculate it? percent yield = (actual yield) divided by (theoretical yield) x 100
The molar mass of CaCO3 is 100.1 g/mol. Therefore, 24.8 g of CaCO3 is equivalent to 0.248 moles. Since the stoichiometry between CaCO3 and CaO is 1:1, the theoretical yield of CaO is also 0.248 moles or 28.05 g. The percent yield is calculated as (actual yield / theoretical yield) x 100%. In this case, the actual yield is 13.1 g, and the theoretical yield is 28.05 g. Thus, the percent yield is (13.1 / 28.05) x 100%, which is approximately 46.7%.
