Aballoon that contains 0.750 moles of gas has a volume of 16.8 l. if the balloon expands to a volume of 25.4 l at a constant pressure and temperature, how many moles of gas would the balloon contain? 0.496 mol 0.882 mol 1.13 mol 6.45 mol

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.
