For this question, lets apply Avagadro's law
when Pressure and temperature are constant, the volume occupied is directly proportional to the number of moles of gases.
![\frac{V}{n} = k](https://tex.z-dn.net/?f=%20%5Cfrac%7BV%7D%7Bn%7D%20%3D%20k)
where V-volume, n-number of moles and k - constant
Therefore at 2 instances
![\frac{V1}{n1} = \frac{V2}{n2}](https://tex.z-dn.net/?f=%20%5Cfrac%7BV1%7D%7Bn1%7D%20%3D%20%20%5Cfrac%7BV2%7D%7Bn2%7D%20)
where V1 and n1 are for 1st instance
and V2 and n2 are for 2nd instance
therefore
![\frac{V1}{n1} = \frac{V2}{n2}](https://tex.z-dn.net/?f=%20%5Cfrac%7BV1%7D%7Bn1%7D%20%3D%20%5Cfrac%7BV2%7D%7Bn2%7D%20)
V1 = 2.4 L
n1 = 3.7 mol
n2 = 3.7 + 1.6 = 5.3 mol
since more He moles are added at the 2nd instance its the sum of the moles.
V2 needs to be calculated
![\frac{2.4}{3.7} = \frac{V2}{5.3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2.4%7D%7B3.7%7D%20%20%3D%20%5Cfrac%7BV2%7D%7B5.3%7D%20)
V2 = 2.4 x 5.3 / 3.7
= 3.4 L
Answer is 1st option 3.4 L
