In which of the following molecular weight determination methods, sensitivity of the measurements decreases as the molecular weight of the solute increases?

Options

A. (a) Elevation of boiling point`//`depression in f.pt.
B. (b) Viscosity
C. (c ) Osmotic pressure
D. (d) None of these

Answer

A

Explanation

`Delta T = (k_(b) xx 1000 xx w)/(m xx W)`, if `m` is more, `Delta T` will be small and thus sensitivity to read `Delta T` accurately decreases.
