Question

The boiling point of benzene is 353.23 k. When 1.80 g of a non volatile solute was dissolved in 90 g of benz8, the boiling point is raised to 354.11 k. Calculate the molar mass of solute and Kb for benzene is 2.53.

Answer 1

Answer:

) The elevation in the boiling point Δ Tb = 354.11 - 353.23 = 0.88 K.The expression for the molar mass of the solute is M2 = Kb × w2 × 1000ΔTb
