Kimberly Wang · Answer 1

a) 37.04% b) 37.04% c) 9.63%

Explanation:

The theoretical percent recovery (Tr), is the total percentage of each compound in the sample. Depending on the technique used to recovery the compounds, the percent recovery will be less than the theoretical, because no technique is 100% efficient.

So, to calculate the theoretical, it will be the mass of the compound divided by the mass of the sample multiplied by 100%.

a) Tr = (250 mg) / (675 mg) * 100%

Tr = 37.04%

b) Tr = (250 mg) / (675 mg) * 100%

Tr = 37.04%

c) Tr = (65 mg) / (675 mg) * 100%

Tr = 9.63%
