At certain Hill-station pure water boils at $99.72$ $° C$ . If $K_{b}$ for water is $0.513$ $° C k g m o l^{- 1}$ . The boiling point of $0.69 m$ solution of urea will be-

Options:

Answer:

Solution:

$Δ T_{b} = K_{b} \times m$

$= 0.513 \times 0.69$

$∴ ∆ T_{b} = 0.354$

So, $T_{b} = 0.354 + 99.72 = 100.074$ $° C$
