224mL

{SO}_{2 ( g )}

298K

and

1atm

is passed through

100mL

0 . 1MNaOH

solution. The non-volatile solute produced is dissolved in

36g

of water. The lowering of vapour pressure of solution (assuming the solution is dilute) (

P{°}_{\left({H}_{2}O\right)} = 24mm

Hg

) is

x \times {10}^{- 2}mm

Hg

the value of

x

is (Integer answer)

Correct answer

Step-by-step solution

Sol $\left(1\right)$

$\begin{cases}{SO}_{2} & + & 2NaOH & \to & {Na}_{2}{SO}_{3} & + & {H}_{2}O \\ \dfrac{224}{0 . 0821 \times 298} = 9 . 2mmol & & 10mmol & & 5mmol & & \\ & & ( L . R . ) & & ( i = 3 ) & & \end{cases}$

${P}^{0} - {P}^{s} = {iX}_{solute}{P}^{0}$

$= 24 \times \dfrac{3 \times 5 \times {10}^{- 3}}{2}$

$= 0 . 18 = 18 \times {10}^{- 3}$ mm of Hg
