Answer 1

Answer:

0.025 L

Explanation:

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

$P_1V_1 = P_2V_2$

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we're finding the final volume

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

We have

$V_2 = \frac{0.05 \times 760}{1520} = \frac{38}{1520} \\ = 0.025$

We have the final answer as

0.025 L

Hope this helps you
