0.1 molal aqueous solution of an electrolyte `AB_(3)` is 90% ionised. The boiling point of the solution at 1 atm is (`K_(b(H_(2)O)) = 0.52 kg " mol"^(-1)`)

A

273.19 K

B

374.92 K

C

376.4K

D

373.19 K

Text Solution

Verified by Experts

The correct Answer is:
D

Total `1 + alpha + alpha + 3alpha =1 +3alpha`
`:. T - 100 = 0.1 (1 +3 xx 0.9) xx 0.52`
`T = 373.19 K`
