The relationship between osmotic pressure at `273 K` when `10 g` glucose `(P_(1)), 10 g` urea `(P_(2))` and `10 g` sucrose `(P_(3))` are dissolved in `250 mL` of water is:

Options

A. `P_(1) gt P_(2) gt P_(3)`
B. `P_(3) gt P_(1) gt P_(2)`
C. `P_(2) gt P_(2) gt P_(3)`
D. `P_(2) gt P_(3) gt P_(1)`

Answer

C

Explanation

`pi prop ( 1)/(" Molecular wt. of solute")`
Molecular wt. of glucose = 180
Molecular wt. of area = 60
Molecular wt. of sucrose =342
