Problem: 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 produces about 6×106 tons of CO2 per year.If it is stored underground as a gas at 37 oC and 90 atm , what volume does it occupy?

FREE Expert Solution

We are asked what volume does  6×106 tons of CO2 occupy at t 37 oC and 90 atm .


Use the modified ideal gas law: 

PV = mRTM


Given: 

P = 90 atm

T = 37°C +273.15 = 310.15 K

M = 44.01 g/mol

R = 0.08206 L-atm/mol-K

m = 6×106 tons
