In the solid-liquid extraction experiment to obtain almond oil, There are 30 g almonds (with a dried content of 82.6%) to be fed into the system. The volume of solvent used in the experiment is 250 ml. The efficiency obtained at the end of the first siphon is 20%. After the cartridge was kept in the oven for a sufficient time, it was weighed as 21.34g (27% of its original Weight is lost). Furthermore, 5% insulation loss is experienced during the distillation phase.

a) Calculate the efficiency at the end of the 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, respectively.

*Each siphon provides a working efficiency of a quarter of the siphon completed before. *

p solvent; 0.659 g/mL, *

Oil content in dried almonds is 54.2% (g/g).
