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
What is a mole?
- 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 × [tex]10^{23}[/tex].
How much is a mole of gas?
22.4 L
At STP (Standard Temperature and Pressure = 0 °C, 1 atm), an ideal gas has a volume of 22.41 L/mol.
What makes something a mole?
- 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.
