Assignment:
A sample of liquefied natural gas, LNG, from Alaska has the following molar composition:
93.5% CH4 , 4.6% C2H6 , 1.2% C3H8 and 0.7% CO2.
Calculate:
(a) The average molecular weight of the LNG mixture.
(b) The weight fraction of CH, in the mixture
(c) The LNG is heated to 320 K and 140 kPa, and vaporizes completely. Estimate the density of the gas mixture under these conditions.
Provide complete and step by step solution for the question and show calculations and use formulas.
