Their numbers look OK. Assuming coal is essentially 100% carbon and using C + O2 --> CO2 Meaning 1 mole (an SI unit!) of coal (carbon) comsumes one mole oxygen giving one mole of carbon dioxide. So you need to figure out how many moles of carbon are in 9000 tons of coal and then figure out the mass for that many moles of CO2. I shall use metric tons to avoid a brain hemmorage. Leaving out factors that cancel anyway you get: 9000 metric tons C X 1 mol/12 g C X 44 g CO2/mol = 33 000 metric tons CO2 Hope this helps, Scott C. > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On > Behalf Of M R > Sent: Tuesday, July 24, 2001 9:00 AM > To: U.S. Metric Association > Subject: [USMA:14579] Carbon Emissions > > > Hi > > In yesterday's (2001-07-23) edition of Washington > Post, there was an article on Nuclear Fusion Power, > and a table of comparison showing the difference > between fusion and thermal power gives this info. > > To power a 1000 MW thermal power plant, it takes 9,000 > tons of coal and it gives of 30,000 tons of co2 > emission. > > Even if 1 unit of carbon combines with 2 units of > oxygen to form co2, it should give < 27,000 tons of > co2 (9,000 tons carbon + 18,000 tons oxygen) , > and if we eliminate the ash and other substances, the > figure should be much lesser.
