Solution

To calculate the percent recovery of the mixture, you need to follow these steps:

  1. 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).

  2. 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%.
