If density of $2$ molal sucrose solution is $1.4{\mathrm{gmL}}^{-1}$ at $25°\mathrm{C},$ find osmotic pressure.

The osmotic pressure of a solution $\left(\mathrm{density} \mathrm{is} 1 \mathrm{g} {\mathrm{mL}}^{-1}\right)$ containing $3 \mathrm{g}$ of glucose (molecular weight =180) in $60 \mathrm{g}$ of water at $15°C$ is

Equimolal solutions of $\mathrm{A}$ and $\mathrm{B}$ show depression in freezing point in the ratio of $2 : 1$. A remains in normal state in solution. $\mathrm{B}$ will be in $\dots \dots \dots$ state in solution:
