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