solution

I have assumed that the asked information is at Normal temperature and pressure conditions i.e. pressure is 1 bar and temperature taken for using the latent heat of vapourisation is 100deg.C i.e. normal boiling point of water at which latent heat of vapourisation is 40.8 kJ/mol

NOTE- you can use the values of LHV=-951.885 kJ/mol and HHV= -1045.725 kj/mol where negative sign shown that this much heat will be RELEASED

Methane is a major component of purified natural gas used for heating and cooking. When 1 mole of methane gas burns with oxygen to produce carbon dioxide and water, 883 kJ is produced. Methane gas has a density of 0.715 g/L at STP. For transport, the natural gas is cooled to -163 ∘C to form liquefied natural gas (LNG) with a density of 0.45 g/mL. A tank on a ship can hold 7.0 million gallons of LNG. A. Draw the...

Carbon Emissions from Natural Gas: Worldwide combustion of methane, CH4 (natural gas), provides about 10.9 × 1016 kJ of energy per year. If methane has an energy content of 39 × 103 kJ/m3 (at STP: Standard Temperature and Pressure), what mass of CO2 is emitted into the atmosphere each year? Also express that emission rate as metric tons of carbon (not CO2) per year. A metric ton, which is 1,000 kg is usually written as tonne to distinguish it from...
