what was the volume of air that has a volume of 6.00L at 120870 Pa, if the original pressure was 250020 Pa?

The answer is 2.90 L

Explanation:

In order to find the original pressure , we use the formula for Boyle's law which is

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we are finding the original volume

From the question

P1 = 250020 Pa

P2 = 120870 Pa

V2 = 6 L

We have

We have the final answer as

2.90 L
