Because 100% means "everything". More than 100% means you're creating something from thin air.
If you have a pie and slice it into quarters, the most you can dish out is 4 pieces, because 4/4 = 1 = 100% To get 125%, you'd have to get an extra piece of pie without cutting the existing pieces or buying extra.
a percent yield will be above 100 if the product used are wet or more likely impure.
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.
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.
Percent Yield.
why don't reactions give us a 100 percent yield?
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
The percent yield is 100(30/34) or 88 %, to the justifiable number of significant digits.
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
the amount of product obtained over the amount possible multiplied by 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.
