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?
