13 liters is the correct answer

13 liters is the final volume of the gas when the temperature and pressure remain constant.

v1/n1 = v2/n2

where,

v1 = initial volume = 8.5 liter

n1= initial mole of gas = 1.2 mole

n2= final mole of gas = 1.2+0.65= 1.85 mole

v2= final volume = ?

8.5 L/1.2 mol = v2/1.85 mol

7 L x 1.85 mol = v2/1.85 mol x 1.85 mol

13 L = v2

v2= 13 liter

A mole is an SI unit used to measure significant numbers of subatomic particles, such as atoms, molecules, or smaller particles.
Any substance has an Avogadro number of molecules in a mole.
The value of the Avogadro number is 6.02214076 × $10^{23}$ .

22.4 L

At STP (Standard Temperature and Pressure = 0 °C, 1 atm), an ideal gas has a volume of 22.41 L/mol.

<h3>What makes something a mole?</h3>

Chemists use the term "mole" because atoms, molecules, and other particles are all very small and require a large amount to even weigh them.
A mole is a measurement of the number of particles present, not their mass.
