If the total domestic electricity is obtained using only "coal" or "LNG" or "gasoline", calculate the annual amount of CO2 released into the atmosphere for each of the three fossil fuels. However, assume that the main components of coal, LNG, and gasoline are C, CH4, and C8H18 (LHV: 30 MJ/kg, 50 MJ/kg, and 50 MJ/kg, respectively), which make up 100%.

Total domestic elctricity consumption is 491300GWh

B. Present each year using the main components of coal, LNG, and gasoline.

C. Calculate the amount of carbon dioxide generated per kilogram of fuel using the annual report derived from B.

D. Calculate the mass of each fuel required for the annual production of electricity in the country. At this time, it is assumed that all the water generated after combustion is released in the form of steam.

E. Calculate the total carbon dioxide emissions if you burn the mass of each fuel derived from
