Answer : The number of moles of gas are in container 2 are 12.008 moles.
Explanation :
According to the Avogadro's Law, the volume of the gas is directly proportional to the number of moles of the gas at constant pressure and temperature.

or,

where,
= initial volume of gas in container 1 = 1.30 L
= final volume of gas in container 1 = 2.33 L
= initial moles of gas in container 2 = 6.70 mole
= final moles of gas in container 2 = ?
Now put all the given values in the above formula, we get the final moles of the gas.


Therefore, the number of moles of gas are in container 2 are 12.008 moles.
