liquid-solid extraction experiment

in the solid liquid extraction experiment to obtain almond oil, There is are 30 g almonds (with a dried content of 82,6 %) to be fed into system. The volume hexane used to experiment in 250 ml.The efficiency obtained at the end of the first siphon is %20 the cartridge was kept in the oven for sufficient time, it was weighed as 21,34 g % 27 original weight is is lost). Furthermore, % 5 insulation loss is experienced during the distillation phase. a-) Calculate the efficiency at the end of second siphon. b-) Find the volume of solvent recovered from the extract phase.? c-) indicate the amount of solute and the volume of solvent remaining in the downstream Each siphon provides a working efficiency of quarter of the siphone. (oil % 54,2 almond q hexane =0,65 g/ml)
