How to calculate percent yield?
-
Mass of Theoretical Yield / Mass of Actual Yield x 100 percent
-
Mass of Actual Yield * Mass of Theoretical Yield * 100 percent
-
Mass of Actual Yield / Mass of Theoretical Yield * 100 percent
-
All of the above
Rate this question:
-
- 4.
In which case, the actual yield becomes more than the theoretical yield?
-
If the solvent is still present in the product.
-
From error weighing the product
-
If the product is impure.
-
All of the above
Rate this question:
-
- 5.
What is the difference between theoretical and actual yield?
-
The actual yield is the total product produced, whereas the theoretical yield is the amount of product based on the complete reaction of the limiting reagent.
-
The theoretical yield is the total product produced, whereas the actual yields are the number of products based on the complete reaction of the limiting reagent.
-
Both A and B
-
None of the above

-
64%
-
74%
-
96%
Rate this question:
-
- 7.
Why is the actual yield lower than the theoretical yield?
-
Because a few reactions truly proceed to completion.
