Calculate the mass of ethane contained in a \(0.3 \mathrm{~m}^{3}\) cylinder at \(60^{\circ} \mathrm{C}\) and 130 bar using the virial equation of state \(Z=1+\frac{B P}{R T}\) for gases, and compare it with the ideal gas law. For ethane, \(T_{\mathrm{C}}=305.3 \mathrm{~K}, P_{\mathrm{C}}=48.72 \mathrm{bar}\), and \(\omega=0.1\).
