$0.63 \mathrm{g}$ of Oxalic acid is dissolved in order to obtain $250{ \mathrm{cm}}^3$ of its solution. Find the normality of this solution. [Oxalic acid: $\left.(\mathrm{COOH}{)}_2·2{\mathrm{H}}_2\mathrm{O}\right]$

The vapour pressure of a solvent decreased by $20 \mathrm{mm}$ of $\mathrm{Hg}$ when a non-volatile solute was added to the solvent. The mole-fraction of the solute in the solution is $0.5$. What should be the mole-fraction of the solvent for the decrease in the vapour pressure needs to be $10 \mathrm{mm}$ of $\mathrm{Hg}$ ?
