Explanation:
It is known that like dissolves like. Therefore, polar solutes are soluble in polar solvents.
For example, salt is a polar compound and water is a polar solvent. Therefore, salt will dissolve in water.
On the other hand, oil is an inorganic solvent and hence, it is unable to dissolve any polar solute.
Therefore, we can conclude that following is true about the effect of polarity on solubility.
- <em>Polar solutes dissolve better in water than in oil.</em>
- <em>Polar solutes have the greatest solubility in polar solvents.</em>

The amu is a unit which means the mass per neutron, So the 74.55 means the mass per mole KCl. So the mole number of 2.330g KCl is 2.330/74.55=0.031 mol. The volume is 0.031/0.1250=0.248 L ≈ 250 mL. So the answer is a.
