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

Options

A. elevation of boiling point /depression in f. pt.
B. viscosity
C. osmotic pressure
D. none

Answer

A

Explanation

`Delta T_(b)=(K_(b)xx1000xx W_(B))/(W_(A) M_(B))`, if` M_(B)` is more , `Delta T_(b) will be small and thus sensitivity to read `Delta T_(b)` accurately decreases.
