Suppose you separate a 3.08 g mixture of sand and salt. You recover 1.39 g of salt and 1.39 g of sand. What is the percent recovery of the mixture?
Question
Suppose you separate a 3.08 g mixture of sand and salt. You recover 1.39 g of salt and 1.39 g of sand. What is the percent recovery of the mixture?
Solution
To calculate the percent recovery of the mixture, you need to follow these steps:
-
First, add the weight of the recovered salt and sand to get the total weight of the recovered mixture. So, 1.39 g (salt) + 1.39 g (sand) = 2.78 g (total recovered mixture).
-
Then, divide the total weight of the recovered mixture by the original weight of the mixture and multiply by 100 to get the percent recovery. So, (2.78 g / 3.08 g) * 100 = 90.26%.
Therefore, the percent recovery of the mixture is 90.26%.
