The final volume will be 38.7 L.

#### Explanation:

We can use **Avogadro's Law** to solve this problem.

The volume of a fixed mass of a gas is directly proportional to the number of moles if the temperature and pressure are constant.

#V/n= k#

In a more usable form, Avogadro's Law becomes

#color(blue)(|bar(ul(color(white)(a/a)V_1/n_1 = V_2/n_2color(white)(a/a)|)))" "#

We can rearrange this equation to get

#V_2 = V_1 × n_2/n_1#

In your problem,

∴
