Problem
A fixed-volume box shows 180 light blue, bent molecules and 12 large purple spheres dispersed uniformly. No other species are present. Which statement most accurately identifies the roles of the two components?
(a) The purple spheres are the solvent because their larger molar mass makes them the medium for the mixture.
(b) Both components are solutes because the presence of two substances means there is no solvent.
(c) The light blue molecules are the solvent because they outnumber the purple spheres.
(d) The light blue molecules are the solute because they are smaller than the purple spheres.
