Question

A sausage sample was found to contain 65% moisture, based on fresh weight. The sausage was dried in an oven until its moisture content was 10%. A 2.0 g portion of the dried sausage was extracted with the Soxhlet method to determine the amount of crude fat. A clean Soxhlet flask weighed 115.0 g. After refluxing for 3 hours using petroleum ether, the solvent was removed by evaporation on the hot plate then completely dried in an oven. The cooled flask was reweighed and gave a weight of 116.5g. Calculate the percentage crude fat in the original sausage (wet weight basis)

I've calculated 75% crude fat in dry weight (10%moisture) but how do I convert that into the wet weight (65% moisture)

Answer 1

consider that the amount of sausage never changed.

did the solvent remove the fat?
