Given moles of a gas =3mol

Volume of baloon=1.5L

Now when we add 0.2moles of the gas then the total moles of the gas becomes 3.2 mol

Suppose the new Volume of the gas =vL

Given that temperature and pressure are at constant then :

But:




V=1.6L

So after adding 0.2 mole of gas new volume of gas is 1.6L
