The gas will exert a pressure of

#### Explanation:

Let's begin by identifying our known and unknown variables.

The first volume we have is

We can obtain the answer using Boyle's Law:

The letters **i** and **f** represent the initial and final conditions. All we have to do is rearrange the equation to solve for the final pressure.

We do this by dividing both sides by

Now all we do is plug in the values and we're done!
