How well can you apply Boyle’s law to this sample of gas that experiences changes in pressure and volume? Assume that temperature and number of moles of gas are constant in this problem.

Using the first volume and pressure reading on the table as V1 and P1, solve for the unknown values in the table below. Remember to use the rules of significant figures when entering your numeric response.
