Answer:

<h2>4.55 L</h2>

Explanation:

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

$P_1V_1 = P_2V_2$

Since we're finding the new volume

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

We have

$V_2 = \frac{195000 \times 3.5}{150000} = \frac{682500}{150000} \\ = 4.55$

We have the final answer as

<h3>4.55 L</h3>

Hope this helps you
