Answer:
The percent yield is calculated by dividing the actual yield by the theoretical yield, and then multiplying by 100 to convert the result to a percentage.
In this case:
Actual yield = 170.81 g
Theoretical yield = 197.3 g
So, the percent yield can be calculated as:
percent yield = (actual yield / theoretical yield) x 100%
percent yield = (170.81 g / 197.3 g) x 100%
percent yield = 86.5%
Therefore, Santiago's percent yield is approximately 86.5%. This means that he obtained 86.5% of the expected amount of product.
