(D) The size of a true solution particle is typically in the range of $10^{-10} \ m$ to $10^{-9} \ m$ (diameter),while a colloidal particle is in the range of $10^{-9} \ m$ to $10^{-6} \ m$ (diameter).Assuming an average diameter for a true solution particle $d_S \approx 10^{-10} \ m$ and for a colloidal particle $d_C \approx 10^{-9} \ m$.The volume $V$ of a spherical particle is given by $V = \frac{4}{3} \pi r^3 = \frac{1}{6} \pi d^3$.Therefore,the ratio of volumes is $\frac{V_C}{V_S} = \frac{d_C^3}{d_S^3} = (\frac{10^{-9}}{10^{-10}})^3 = (10^1)^3 = 10^3$.Thus,the ratio is approximately $10^3$.

The volume of a colloidal particle,$V_C$,as compared to the volume of a solute particle in a true solution,$V_S$,could be:
