Answer: 1.13 mol
Explanation:
Avogadro's Law: This law states that volume is directly proportional to the number of moles of the gas at constant pressure and temperature.
(At constant temperature and pressure)
where,
= initial volume of gas = 16.8 L
= final volume of gas = 25.4 L
= initial number of moles = 0.750
= final number of moles = ?
Now put all the given values in the above equation, we get the final pressure of gas.
Therefore, the final moles will be 1.13.
