#### Explanation:

Let's identify the known and unknown variables:

- Initial Volume

- Final Volume

- Initial Pressure

- Final Pressure

We can obtain the answer using Boyle's Law

The numbers **1** and **2** represent the initial and final conditions, respectively.

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!
