A 33.0-L cylinder contains 481 g O2(g) at 22.5°C. What mass of O2(g) must be released to reduce the pressure in the cylinder to 6.16 atm, assuming the temperature remains constant?

Thanks! :D

Jin? Abby?
Use PV = nRT and calculate n to reduce the pressure to that indicated, then n = grams/molar mass. You know n and molar mass, solve for grams.
