What is the solubility of gas in water at $$25^{\circ} \mathrm{C}$$ if partial pressure is 0.346 bar [Henry's law constant is $$[0.159 \mathrm{~mol} \mathrm{~dm}^{-3} \mathrm{~bar}^{-1}]$$ ?

The partial vapour pressure of any volatile component of a solution is equal to the vapour pressure of the pure component multiplied by its mole fraction in the solution is called

Which among the following solutions has minimum boiling point elevation?

Calculate osmotic pressure of solution of 0.025 mole glucose in $$100 \mathrm{~mL}$$ water at $$300 \mathrm{~K}$$. $$\left[\mathrm{R}=0.082 \mathrm{~atm} \mathrm{dm} \mathrm{mol}^{-1} \mathrm{~K}^{-1}\right]$$
