Question

The oil in sunflower whose mass composition is 7% water, 37% oil and 56% solids will be extracted with pure hexane. 100 kg of sunflower per hour enters the extractor and 1 kg of hexane per 1 kg of solid matter. It contains the residue from the extractor and the solvent to be 0.30 kg solution / 1 kg solid substance. The solution in the residue contains 15% oil, 12% water and 73% hexane by mass. According to this,
a) The mass of the residue coming out of the extractor and its percentage composition by mass,
b) The mass and percentage composition by mass of the obtained solution (hexane + oil + water),
c) Calculate what% of the starting oil was extracted.
