Question

A non-volatile and non electrolytic solute is
dissolved in water at 100°C. If vapour pressure of
solution at 100°C is 684 mm Hg. The boiling point
of this solution is X°C. If molal elevation constant
and boiling point of water is 0.52 Km- and 100°C
respectively. The value of X is (vapour pressure of
water at 100°C is 760 mm Hg and assume solution
is ideal]
(1) 101.21
(2) 102.21
(3) 103.21
(4) 104.21
​

Answer 1
