Using the nutritional information provided, what is the theoretical mass percent of fat in the 10 g sample of Snicker's bar? What was the percent recovery of fat in this experiment?Explanation / Answer
m = 1.96 g of fat
m = 10 g of snickers
theoretical amount -->
57 g of snicker = 13.6 g of fat
10 g of snicker = 10/57*13.6 = 2.386 g of fat (theoretical)
%yield = real/theoretical * 100% = 1.96 /2.386 *100
%yield = 82.145 % recovery
