The daily production of carbon dioxide from an 880 MW coal-fired power plant is estimated to be 31,000 tons. A proposal has been
miskamm [114]

Answer:

1.3578\times 10^{8} m^3 volume of carbon dioxide gas would be collected during a one-year period.

Explanation:

Mass of carbon dioxide gas collected in a day = 31,000 Tonn

1 Tonn = 1000 kilogram

31,000 Tonn = 31,000\times 1000 kg=31,000,000 kg

Specific volume of the carbon dioxide gas = V_s

V_s=0.012 m^3/kg

Volume of carbon dioxide gas collected in a day = V

V=V_s\times 31,000,000 kg=0.012 m^3/kg\times 31,000,000

V=372,000 m^3

1 year = 365 days

Volume of carbon dioxide gas collected in a year = V'

V'=372,000\times 365 m^3=1.3578\times 10^{8} m^3

1.3578\times 10^{8} m^3 volume of carbon dioxide gas would be collected during a one-year period.
