Question

Carbon dioxide, which is recognized as the major contributor global warming as a "greenhouse gas", formed when fossil fuel are combusted, a electrical power plants fueled by coal, natural gas. One potential way 10 reduce the amount of CO_2 added to the atmosphere is to store it as a compressed gas in underground formations. Consider a 1000-megawatt coal fired power plant that produces about 5 times 10^5 tons of CO_2 per year Assuming ideal gas behavior, 1.00 atm and 37 degree C, calculate the volume of CO_2 produced by this power plant. Express your answer using one significant figure. If the CO_2 is stored underground as a quid at 10 degree C and 120 atm and a density of 1.2 g/cm^3, what volume does it possess? Express your answer using one significant figure it is stored underground as a gas at 34 degree C and 80 atm, what volume does it occupy? Express your answer using one significant figure.

Explanation / Answer

part A)

mass of CO2 = 5 x 10^5 tonns

= 5 x 10^5 x 907185 g

                    = 4.54 x 10^11 g

moles of CO2 = 4.54 x 10^11 / 44 = 1.03 x 10^10

P V = n R T

1 x V = 1.03 x 10^10 x 0.0821 x 310

V = 3 x 10^11 L

volume of CO2 = 3 x 10^11 L

part B)

P V = n R T

120 x V = 1.03 x 10^10 x 0.0821 x 288

V = 2 x 10^9 L

part C)

P V = n R T

80 x V = 1.03 x 10^10 x 0.0821 x 307

V = 3 x 10^9 L
