The experimentally determined density of \( \mathrm{O}_{2} \) at 100 . bar and \( 298 \mathrm{~K} \) is \( 151 \mathrm{~g} \cdot \mathrm{L}^{-1} \). Estimated \( z \) from the figure below. The critical constants \( T_{c} \) and \( P_{c} \) of \( \mathrm{O}_{2} \) are \( 154.58 \mathrm{~K} \) and \( 50.43 \) bar, respectively. The compression factor plotted as a function of \( P_{r} \) for selected values of \( T_{r} \). Values of \( T_{r} \) are indicated adjacent to the curves. The curves were calculated using the van der Waals equation of state. Express your answer using two significant figures.
