Chemistry - Liquid Solution Question with Solution | TestHub

1.80 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 K . The molar mass of solute A is $\dots \mathrm{g}{\mathrm{mol}}^{-1}$.

[Given: Freezing point of ethanol is 156.0 K . Density of ethanol is $0.80\mathrm{g}{\mathrm{cm}}^{-3}$. Freezing point depression constant of ethanol is $2.00\mathrm{K}\mathrm{kg}{\mathrm{mol}}^{-1}$ ]
