Answer:

0.47 atm

Explanation:

The final pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we are finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

From the question we have

[tex]P_2 = \frac{2.5 \times 1.6}{8.6} = \frac{4}{8.6} \\ = 0.465116...[/tex]

We have the final answer as

0.47 atm

Hope this helps you
