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

Answer»

`(V_c)/(V_s) = 10^3`
`(V_c)/(V_s) = 10^(-3)`
`(V_c)/(V_s) = 10^(23)`
`(V_c)/(V_s) = 1`

Solution :SIZE of colloidal particles = 1 to 100 n.m (SAY = 10 nm)
`V_c = 4/3 pi r^3 = 4/3 pi (10)^(3)`, size of TRUE solution particles = 1 nm
`V_3 = 4/3 pi (1)^(3) , (V_c)/(V_s) = 10^3`
