Question

Samantha very carefully measured out 7.99g of the product she created in lab. Her pre-lab work showed she was expecting 8.50 g. What is Samantha's percent yield?

Answer 1

The percent yield is a measure of how much of the expected product was actually obtained in an experiment. It is calculated by dividing the actual yield by the theoretical yield (what was expected), and multiplying by 100 to convert the result to a percentage.

In this case, Samantha measured out 7.99 g of the product, but was expecting 8.50 g based on her pre-lab work. So:

actual yield = 7.99 g

theoretical yield = 8.50 g

Using these values, we can calculate the percent yield as:

percent yield = (actual yield / theoretical yield) x 100%

percent yield = (7.99 g / 8.50 g) x 100%

percent yield = 94.12%

Therefore, Samantha's percent yield is approximately 94.12%. This means that she obtained 94.12% of the expected amount of product.
