Because the yield can never exceed the quantity in the original mix. ie if an ore sample contains 3% of a mineral, if that 3% is extracted totally, then the yield is 100% and cannot be more because that's all there is in the sample.
Percentage yield = (Actual yield / Theoretical yield) x 100% The percentage yield for a reaction is a value between 0 to 100 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
You did something wrong in your calculation or you have some impurity. You never get 100% yield.
Impurities in the substance can cause a greater percent yield. I recommend redoing the lab for better results.

Percent Yield.
a percent yield will be above 100 if the product used are wet or more likely impure.
why don't reactions give us a 100 percent yield?
The percent yield can be calculated using the formula: (actual yield / theoretical yield) x 100%. Plugging in the numbers, we get (47.87 g / 50.26 g) x 100% = 95.28%.
Do you need it? Are you being told to calculate it? percent yield = (actual yield) divided by (theoretical yield) x 100
Percent yield is calculated as (actual yield / theoretical yield) * 100%. In this case, the actual yield is 30g and the theoretical yield is 34g. So, percent yield = (30g / 34g) * 100% = 88.24%.
Percentage yield = (Actual yield / Theoretical yield) x 100% The percentage yield for a reaction is a value between 0 to 100 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
Percent yield can be calculated using the formula: (actual yield / theoretical yield) x 100%. In this case, it would be (8.67 g / 11.22 g) x 100% = 77.1% yield.
Actual
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.
