Answer
Acetone will dissolve more quickly. The vapor pressure is greater in the acetone.
Work Step by Step
Water undergoes hydrogen bonding so it will have stronger intermolecular forces compared to acetone that only undergoes dipole-dipole forces. The weaker the forces, the faster the evaporation rate allowing acetone to evaporate faster. Since acetone has weaker intermolecular forces, it will also have a higher vapor pressure because as intermolecular forces decrease, vapor pressure increases.
