Question

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:
A. (a) `P_(1) gt P_(2) gt P_(3)`
B. (b) `P_(3) gt P_(1) gtP_(2)`
C. ( c) `P_(2) gt P_(1) gt P_(3)`
D. (d) `P_(2) gt P_(3) gt P_(1)`

Answer 1

Correct Answer - C
`P = (w)/(m.V)ST`, since `w, V,T` are constant
Thus `P prop (1)/(m)`
