Answer:
[tex]\boxed {\boxed {\sf A. \ 38.1 \%}}[/tex]
Explanation:
Percent yield is the ratio of the amount actually produced to how much could theoretically be produced. It is found using this formula:
[tex]\% \ yield = \frac{actual \ yield}{theoretical \ yield} *100[/tex]
For this reaction, the theoretical or expected yield is 325.0 grams. The actual yield is 123.8 grams.
[tex]\% \ yield = \frac{ 123.8 \ g }{325.0 \ g }*100[/tex]
Divide.
[tex]\% \ yield = 0.380923077 *100[/tex]
[tex]\% \ yield = 38.0923077[/tex]
Round to the nearest hundredth. The 9 in the hundredth place tells us to round the 0 to a 1 .
[tex]\% \ yield \approx 38.1[/tex]
The percent yield is about 38.1%
Answer:
38.1%
