Plot the data given in Table 5.3 for oxygen at 0°C to obtain an accurate molar mass for O 2 . To do this, calculate a value of the molar mass at each of the given pressures from the ideal gas law (we will call this the “apparent molar mass” at this pressure). On a graph show the apparent molar mass versus the pressure and extrapolate to find the molar mass at zero pressure. Because the ideal gas law is most accurate at low pressures, this extrapolation will give an accurate value for the molar mass. What is the accurate molar mass?
