Question

Two closed vessels contain chlorine gas at the same conditions of temperature and

Answer 1

The number of moles : 12.01

Further explanation

Given

V₁ = 1.3 L contains 6.7 mol of gas(n₁)

V₂ = 2.33 L

Required

The number of moles

Solution

Avogadro's : at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles  

$\tt \dfrac{V_1}{V_2}=\dfrac{n_1}{n_2}$

$\tt \dfrac{1.3}{2.33}=\dfrac{6.7}{n_2}\\\\n_2=12.01$
