Question

A reaction was suppose to produce 20 L of gas. Only 12 litters of gas were produced in the lab. What is the percent yield for this reaction?

Answer 1

`\boxed {\boxed {\sf 60 \%}}`

Step-by-step explanation:

Percent yield is a ratio of the actual yield to the theoretical yield. It is found using this formula:

`\% \ yield= \frac {actual \ yield}{theoretical \ yield} *100`

The actual yield is 12 liters, because that was actually produced in the lab.

The theoretical yield is 20 liters, because that was the expected yield.

`\% \ yield= \frac {12 \ L}{20\ L} *100`

`\% \ yield= 0.6*100`

`\% \ yield= 60`

For this reaction, the percent yield is 60%.
