Two closed vessels contain chlorine gas at the same conditions of temperature and pressure, so if the first vessel whose volume = 1.3 L contains 6.7 mol of gas,
what is the number of moles in the second vessel whose volume = 2.33 L ?

The number of moles : 12.01

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  

i believe the answer is 5,000
