Answer:
(Percent yield × theoretical yield) ÷ 100.
Explanation:
∵ percent yield of the reaction = [(actual yield)/(theoretical yield)] x 100.
∴ actual yield = [(percent yield of the reaction) x (theoretical yield)]/100.
So the right choice is: (Percent yield × theoretical yield) ÷ 100 .
Answer : The correct option is, [tex]\frac{(\text{Percent yield}\times \text{Theoretical yield})}{100}[/tex]
Explanation :
The formula used for the percent yield will be :
[tex]\text{Percent yield}=\frac{\text{Actual yield}}{\text{Theoretical yield}}\times 100[/tex]
or,
[tex]\text{Actual yield}=\frac{(\text{Percent yield}\times \text{Theoretical yield})}{100}[/tex]
For example : If we are given that the percentage yield of a sample is 94.92% and the theoretical yield is 83.475 g. Now calculate the actual yield of the sample.
By using formula we get the value of actual yield.
[tex]\text{Actual yield}=\frac{(94.92\times 83.475)}{100}=79.23g[/tex]
Thus, the actual yield is, 79.23 g.
Hence, the formula used to calculate the actual yield can be, [tex]\frac{(\text{Percent yield}\times \text{Theoretical yield})}{100}[/tex]
