a.)

Three liquids containing furfural, water, and ethylene
glycol were mixed in a container. Determine how many phases the system has if the three liquids have these compositions:

Liquid	mA (g)	mB (g)	mc (g)
furfural	20	22	102
water	16	20	33
ethylene glycol	21	18	48

b.) If the mixture in (LETTER a) has only one phase, how many grams of furfural must be added to obtain a two-phase system. If it has two phases, determine the compositions of the extract and raffinate phases.

The solute is ethylene glycol, and furfural is the solvent that removes ethylene glycol from a binary mixture with water. The furfural-rich phase is called the extract while the water-rich phase is called the raffinate. Mass fraction water Raffinate P. Mass fraction ethylene glycol Extract E,
