Vedclass · Answer

(D) The diameter of a particle in a true solution is typically $1 \ \mathring{A}$ to $10 \ \mathring{A}$,while the diameter of a colloidal particle ranges from $10 \ \mathring{A}$ to $1000 \ \mathring{A}$.
Taking the lower limit of the diameter for both,let $d_s = 1 \ \mathring{A}$ and $d_c = 10 \ \mathring{A}$.
The ratio of volumes is given by the ratio of the cubes of their radii (or diameters):
$V_c/V_s = (d_c/d_s)^3 = (10/1)^3 = 10^3$.

What is the ratio of the volume of a colloidal particle $(V_c)$ to the volume of a particle in a true solution $(V_s)$?
