Question

A chemical reaction that is expected to form 325.0 gof product only forms 123.8 g of product. What is the percent yield of this reaction?

38.1%
61.9%
201.2%
262.5%

Answer 1

38.1%

Step-by-step explanation:

Answer 2

`\boxed {\boxed {\sf A. \ 38.1 \%}}`

Step-by-step explanation:

Percent yield is the ratio of the amount actually produced to how much could theoretically be produced. It is found using this formula:

`\% \ yield = (actual \ yield)/(theoretical \ yield) *100`

For this reaction, the theoretical or expected yield is 325.0 grams. The actual yield is 123.8 grams.

`\% \ yield = ( 123.8 \ g )/(325.0 \ g )*100`

Divide.

`\% \ yield = 0.380923077 *100`

`\% \ yield = 38.0923077`

Round to the nearest hundredth. The 9 in the hundredth place tells us to round the 0 to a 1 .

`\% \ yield \approx 38.1`

The percent yield is about 38.1%
