Answer:

Explanation:

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

$P_1V_1 = P_2V_2$

Since we are finding the new volume

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

From the question we have

$V_2 = \frac{207000 \times 0.05}{101000} = \frac{10350}{101000} \\ = 0.102475...$

We have the final answer as
