Question

A

Answer 1

Answer:

159.09 mmHg

Explanation:

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

$P_2 = \frac{P_1V_1}{V_2}$

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

From the question we have

$P_2 = \frac{125\times3.50 }{2.75} = \frac{437.5}{2.75} \\ = 159.090909...$

We have the final answer as

159.09 mmHg

Hope this helps you
