Answer : The final volume of gas will be, ![2.36\times 10^9L](https://tex.z-dn.net/?f=2.36%5Ctimes%2010%5E9L)
Explanation :
Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
![V\propto T](https://tex.z-dn.net/?f=V%5Cpropto%20T)
or,
![\frac{V_1}{V_2}=\frac{T_1}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BV_1%7D%7BV_2%7D%3D%5Cfrac%7BT_1%7D%7BT_2%7D)
where,
= initial volume of gas = ![2.74\times 10^9L](https://tex.z-dn.net/?f=2.74%5Ctimes%2010%5E9L)
= final volume of gas = ?
= initial temperature of gas = ![20.0^oC=273+20.0=293K](https://tex.z-dn.net/?f=20.0%5EoC%3D273%2B20.0%3D293K)
= final temperature of gas = ![-20.0^oC=273+(-20.0)=253K](https://tex.z-dn.net/?f=-20.0%5EoC%3D273%2B%28-20.0%29%3D253K)
Now put all the given values in the above formula, we get the final volume of the gas.
![\frac{2.74\times 10^9L}{V_2}=\frac{293K}{253K}](https://tex.z-dn.net/?f=%5Cfrac%7B2.74%5Ctimes%2010%5E9L%7D%7BV_2%7D%3D%5Cfrac%7B293K%7D%7B253K%7D)
![V_2=2.36\times 10^9L](https://tex.z-dn.net/?f=V_2%3D2.36%5Ctimes%2010%5E9L)
Therefore, the final volume of gas will be, ![2.36\times 10^9L](https://tex.z-dn.net/?f=2.36%5Ctimes%2010%5E9L)
16.00 grams of oxygen
since in one mole the mass would be the molecular mass, which is found on the periodic table
<em>FeCl2</em><em> </em><em>+</em><em> </em><em>Na2CO3</em><em> </em><em>=</em><em> </em><em>FeCO3</em><em> </em><em>+</em><em> </em><em>2</em><em>N</em><em>a</em><em>C</em><em>l</em>
