Mass Transfer In a single stage extraction process, 10 kg of pure solvent S (containing no solute A) is mixed with 30 kg of feed F containing A at a mass fraction xf = 0.2. The mixture splits into an extract phase E and a raf-finate phase R containing A at xB = 0.5 and xR = 0.05 respectively. The total mass of the extract phase is (in Kg) 10 8.25 8.89 6.89 10 8.25 8.89 6.89 ANSWER DOWNLOAD EXAMIANS APP
