Δ Tb=2.2=i × 2.2 × 1 ⇒ i=1

Q. Which of the following aqueous solution will have the boiling point $102. 2^{\circ} C$ ? The molal elevation constant for water is $2.2 K k g m o l^{- 1}$ .

$1 m C H_{3} COO H$

$1 m N a Cl$

$1 M N a Cl$

$1 m$ glucose

$Δ T_{b} = 2.2 = i \times 2.2 \times 1$
$\Rightarrow i = 1$
