Four solutes are added to a solvent. All solutes have the same mass and solubility. The surface areas of four solutes are 2 mm squared , 4 mm squared , 6 mm squared , and 10 mm squared Which solute will dissolve the quickest?

A greater surface area exposes more of the solute to the solvent at once, increasing the rate of dissolving. Since the solutes have the same mass and solubility, the one with a surface area of 10 mm² will dissolve quickest.
