Calculation of the Fugacity of a Gas Using the Virial Equation Compute the fugacities of pure ethane and pure butane at 373.15 K and 1, 10, and 15 bar, assuming the virial equation of state can describe these gases at these conditions.

Data: BET (373.15 K) = -1.15 x 10-4 m/mol

BBU (373.15 K) = -4.22 x 10-4 m/mol
