4.624 grams of a mixture of a metal, wood chips, salt and sand are separated. If 0.982 grams of metal, 0.833 grams of wood chips, 0.623 grams of salt and 0.777 grams of sand are recovered after the separation, what is the % recovery of the 4 substances? What is the % component for each of the four substances

To calculate the percentage recovery of the four substances, we first need to add up the weights of the recovered substances.

0.982 grams (metal) + 0.833 grams (wood chips) + 0.623 grams (salt) + 0.777 grams (sand) = 3.215 grams

Next, we divide the total weight of the recovered substances by the original weight of the mixture and multiply by 100 to get the percentage recovery.

(3.215 grams / 4.624 grams) * 100 = 69.54%

So, the percentage recovery of the four substances is 69.54%.

To calculate the percentage component for each of the four substances, we divide the weight of each substance by the original weight of the mixture and multiply by 100.

For metal: (0.982 grams / 4.624 grams) * 100 = 21.24% For wood chips: (0.833 grams / 4.624 grams) * 100 = 18.02% For salt: (0.623 grams / 4.624 grams) * 100 = 13.47% For sand: (0.777 grams / 4.624 grams) * 100 = 16.81%

So, the percentage component for metal is 21.24%, for wood chips is 18.02%, for salt is 13.47%, and for sand is 16.81%.
