Answer:
Percentage mass of fat(grams) ≈ 78.60 %
Explanation:
The mass of the whole butter is 19.g grams, this means the mass of the original butter before solvent extraction was 19.6 grams.
Mass of original butter = 19.6 grams
Following the extraction of fat, the remaining sample of the original butter mass reduced to 4.2 grams . This means the mass of the fat extracted from the butter is 19.6 grams - 4.2 grams = 15.4 grams.
The mass of the fat = 15.4 grams
Percentage mass of fat(grams) = mass of fat/mass of original butter × 100
Percentage mass of fat(grams) = 15.4/19.6 × 100
Percentage mass of fat(grams) = 1540/19.6
Percentage mass of fat(grams) = 78.5714285714
Percentage mass of fat(grams) ≈ 78.60 %
