Carbon dioxide, which is recognized as the major contributor to global warming as a greenhouse gas, is formed when fossil fuels are combusted, as in electrical power plants fueled by coal, oil, or natural gas. One potential way to reduce the amount of CO2 added to the atmosphere is to store it as a compressed gas in underground formations.
Consider a 1000-megawatt coal-fired power plant that burns about 6.00*10^6 metric tons of coal per year,
(a) assuming final conditions of 1.10 atm, and 27.0 C, calculate the volume of CO2 produced by this power plant
(b) If the CO2 is stored underground as a liquid at 10.0 C and 120.0 atm and density of 1.20 g/ml what volume does it possess?
(c) If it is stored underground as a gas at 36.0 C and 90.0 atm, what volume does it occupy?
