Question

A sample of air from inside a facility (air pressure 1.00 atm) is compressed so it can be "scrubbed" (have
its CO2 removed). The initial volume of air taken in is unknown, but when it is inside the scrubber at
pressure 2.8 atm) is measured as taking up a volume of 217 L. What was the sample's initial volume?

Answer 1

Answer:

608 L

Explanation:

Using Boyle's law equation as follows:

P1V1 = P2V2

Where;

P1 = initial pressure (atm)

P2 = final pressure (atm)

V1 = initial volume (L)

V2 = final volume (L)

According to the information provided in this question;

P1 = 1.00atm

P2 = 2.8atm

V1 = ?

V2 = 217L

Using P1V1 = P2V2

V1 = P2V2/P1

V1 = 2.8 × 217/1

V1 = 607.6/1

V1 = 607.6

The initial volume is 608 L
