SUMMARY
The calculation of the mass of oxygen in a cylinder using the Ideal Gas Law involves the equation PV=nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature in Kelvin. In this discussion, the pressure of 148 atm and volume of 2.80 liters were used, leading to an initial calculation of 5.5 grams of oxygen, which was incorrect due to unit conversion errors. The correct approach requires converting pressure to Pascals and volume to cubic meters, resulting in a mass calculation of 558 grams.
