If $\displaystyle 8$ g of a non-electrolyte solute is dissolved in $\displaystyle 114$ g of n-octane to reduce its vapour pressure to $\displaystyle 80 \%$, the molar mass (in $\displaystyle \mathrm{g} \mathrm{mol}^{-1}$ ) of the solute is [Given that molar mass of n-octane is $\displaystyle 114 \mathrm{~g} \mathrm{~mol}^{-1}$ ]
