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.
