Answer:
[tex]V_2=28.6L[/tex]
Explanation:
Hello there!
In this case, according to the given information, it is possible for us to solve this problem via the Avogadro's gas law as a way to understand the volume-moles behavior as a directly proportional relationship:
[tex]\frac{V_2}{n_2}=\frac{V_1}{n_1}[/tex]
In such a way, we solve for the final volume as shown below:
[tex]V_2=\frac{V_1n_2}{n_1} \\\\V_2=\frac{40.0L*50.0mol}{70.0mol}\\\\V_2=28.6L[/tex]
