what is the percent of recovery if you begin with 0.421 grams of copper and recover 0.325 grams?

%recovery = (0.325/0.421)*100 = ?

77.2

To calculate the percent recovery, you need to find the ratio of the recovered amount to the initial amount, and then multiply by 100 to express it as a percentage.

First, determine the ratio by dividing the recovered amount by the initial amount:
Ratio = Recovered amount / Initial amount

In this case, the recovered amount is 0.325 grams, and the initial amount is 0.421 grams.
Ratio = 0.325 grams / 0.421 grams

Now calculate the percentage by multiplying the ratio by 100:
Percentage = Ratio * 100

To find the percent of recovery, you can use the following steps:

1. Divide the recovered amount by the initial amount: 0.325 grams / 0.421 grams = 0.7715
2. Multiply the result by 100 to get the percentage: 0.7715 * 100 = 77.15%

Therefore, the percent recovery is approximately 77.15%.
