Answer:

The answer is 2100 mmHg

Explanation:

The new 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{240 \times 700}{80} = \frac{168000}{80} = \frac{16800}{8} \\ [/tex]

We have the final answer as

2100 mmHg

Hope this helps you
