Question

A compressed air tank carried by scuba divers has a volume of 9.0 L and a pressure of 140 atm at 20∘C.

If the gas was instead in a cylinder with a floating, massless, frictionless piston, what would the volume of the gas be (in liters) at STP?

Express the volume in liters to two significant digits.
