Question 1 :
One mole of non-volatile solute is dissolved in two mole of water. The vapour pressure of the solution relative to that of water is :

Question 2 :
At {tex} 15 ^ { \circ } \mathrm { C } {/tex} and {tex}1{/tex} atmosphere partial pressure of hydrogen, {tex} 20 \mathrm { mL } {/tex} of hydrogen measured at STP dissolves in {tex} 1 \mathrm { L } {/tex} of water. If water at {tex} 15 ^ { \circ } \mathrm { C } {/tex} is exposed to a gaseous mixture having a total pressure of {tex} 1500 \mathrm { mm } {/tex} of Hg (excluding the vapour pressure of water) and containing {tex} 80 \% {/tex} hydrogen by volumne, then the volume of hydrogen measured at STP that will dissolve in {tex} 1 \mathrm { L } {/tex} of water is
