Passage / Comprehension

A solid vessel contains $7.1 g$ of chlorine gas at ambient pressure at $T K$ . The vessel is kept in a bath which is $3 0^{\circ}$ hotter. In order to maintain the original pressure, some gas is withdrawn and is found to occupy $246 m L$ at $1 a t m$ at $27℃$ . $[R = 0.082 a t m \cdot L \cdot m o l^{- 1} \cdot K^{- 1}]$

If the gas is not withdrawn, the pressure increases by $0.11 a t m$ . What would be the original (ambient) pressure?

Options:

Answer:

Solution:

$n_{C l_{2}} = 0.1$

$n_{C l_{2 w i t h d r a w}} n_{C l_{2 l e f t}} = \frac{1 \times 246 \times 1 0 ^{- 3}}{0.082 \times 300} = 0.01 = 0.09$
