The measured volumetric flow rate of ethane at 10.0 atm absolute and 35 oC is 1.00 × 103 L/h. Using an estimated value of the virial equation of state truncated after the second term, calculate
(a) The specific molar volume (L/mol)
(b) The compressibility factor
(c) The mass flow rate of ethane (kg/h)
After tert-amyl chlorid has been distilled, one notices that there is some liquid remaining and this liquid distills at approximately 373.15K.
