Calculate the percent recovery of copper if: 7.26 g is the initial amount and 8.61 g is the amount recovered?

it is similar to percent increase/decrease formulas.

initial amount= 7.26 grams
final amount= 8.61 grams

percent increase= |8.61-7.26|/ 7.26

To calculate the percent recovery of copper, you need to use the following formula:

Percent recovery = (Amount recovered / Initial amount) × 100%

Let's substitute the given values into the formula:

Percent recovery = (8.61 g / 7.26 g) × 100%

Now, divide the amount recovered by the initial amount:

Percent recovery = 1.18

Finally, multiply the result by 100% to find the percentage:

Percent recovery = 118%

Therefore, the percent recovery of copper in this case is 118%.
