Natural gas is a mixture of hydrocarbons, primarily methane (CH4) and ethane (C2H6). A typical mitxture might have Xmethane=0.915 and Xethane=0.085. What are the partial presssures of the two gases in a 15.00-L container of natural gas at 20. C and 1.44 atm? Assuming complete combustion of both gases in the natural sample, what is the total mass of water formed?
