# If 32 g of an unknown molecule ( assumed to be unionised in solution ) dissolved in 200g of $H_2O$, then elevation in boiling point is found to be 1.04$^{\large\circ}$C. Find out the molar mass of the unknown molecule ($K_b$ given for $H_2O = 0.52kg mol^{−1}$)

## 1 Answer

80 g / mole
Hence (B) is the correct answer.
