Let's say i make a solution with alcohol and, say, 5g of a non-reactive chemical compound. if i evaporate the some if alcohol, will there always be 5g of the chemical left in the alcohol? does it depend on the compound?

It depends on the compound.

Step-by-step explanation:

If the solute is volatile, like methanol, then some of it will evaporate along with the ethanol. The solution will contain less than 5 g of solute as the ethanol evaporates.

If the solute is non-volatile, like glycerol, then none of it will evaporate along with the ethanol. The solution will contain 5 g of solute as the ethanol evaporates.

the dissolution of polymer can be thermodynamically described in 2 steps.
