If you consider the ideal gas law to be an acceptable approximation for substances that have compressibility factors within 10% of 1 (i.e., between 0.90 and 1.10), determine the range of acceptable pressures for ideal gas behavior for a gas with a temperature of 300 K if the gas is (a) hydrogen, (b) oxygen, and (c) carbon dioxide.
Given: T = 300 K, 0.9 ? Z ? 1.10 What will be an ideal response?
