The law of corresponding states implies that all real gases act similarly under the same reduced conditions. Thus a plot such as the one below can be used to determine the compressibility factor for any gas. Using the results of Problem 3 above, determine z for O2 under the given conditions and calculate the amount of O2 in the gas cylinder.
