# In a gaseous or liquid solution, is the the volume of the solvent greater to or less than the volume of the solute?

In gaseous solution, i.e. a mixture of two gases, the volume of solvent gas should be precisely the same as the volume of the solute gas. $\text{Dalton's Law of Partial Pressures}$ assures us that in a gaseous mixture, the partial pressure of each component gas is the same as the pressure it would exert if it alone occupied the container.
