$1.80 \mathrm{g}$of solute A was dissolved in$62.5 {\mathrm{cm}}^3$of ethanol and freezing point of the solution was found to be$155.1 \mathrm{K}$. The molar mass of solute$\mathrm{A}$is${\mathrm{gmol}}^{-1}$. [Given: Freezing point of ethanol is$156.0 \mathrm{K}$. Density of ethanol is$0.80 \mathrm{g} {\mathrm{cm}}^{-3}$. Freezing point depression constant of ethanol is$2.00 \mathrm{K} \mathrm{kg} {\mathrm{mol}}^{-1}$]
