Question

When nh3 is prepared from 28 g n2 and excess h2, the theoretical yield of nh3 is 34 g. when this reaction is carried out in a given experiment, only 30. g is produced. what is the percentage yield?

Answer 1

To solve, you divide the produced (actual yield) by the theoretical. Finally multiply by 1 to find the percent.


`(30gNH3)/(34gNH3) = .88`


`.88 * 100= 88`%

88% is the percent yield.

Answer 2

Answer: 88%

Step-by-step explanation:

Percentage yield is the ratio of experimental to the theoretical yield in terms of percentage.

percentage yield =
`\frac{\text {Experimental yield}}{\text{Theoretical yield}}* 100`

Given :

Experimental yield = 30 g

Theoretical yield = 34 g

percentage yield =
`(30)/(34)* 100=88\%`

Therefore, the percentage yield of the reaction is 88%
