What volume of sulfuric acid (1.84 g/mL) would be produced in that year after the resulting sulfur dioxide reacted with atmospheric oxygen and water vapor (in liters)?

One metric ton (1000 kg) of coal is required to produce 7.3 MW-hr of electrical energy. In 1993, the Thomas Hill power plant (a small, coal-fired plant supplying rural electric cooperatives) produced 7100000.0 MW-hr. If low sulfur (1%) coal were used, and the gaseous effluent were the only means of discharging the sulfur, what volume of sulfuric acid (1.84 g/mL) would be produced in that year after the resulting sulfur dioxide reacted with atmospheric oxygen and water vapor (in liters)?

Please do ONLY if you're positive! The program I use is very picky :(

13. Taking the mass of the atmosphere to be 5.6E15 metric tons, what mass of carbon must be burned in order to increase the average carbon dioxide level in the atmosphere by 0.5ppm by volume (in metric tons)?

re: daytime concentration of OH; molar concentration

25. The daytime concentration of OH in continental air averages 6.9E6 molecules per cubic centimeter. Calculate its molar concentration.

Word prob inv. ppm, STP, concentrations

28. The air inside a garage was found to contain 28.00 ppm CO by volume at standard temperature and pressure (STP). What is the concentration of CO in ppm by mass? Please accept ONLY if you're positive! My computer program is very picky and likes to tell me the answers are wrong!

calculate mass % of meth, eth, and MTBE in gasoline. I have NO clue where to even start!

38. Calculate the mass percent of methanol, ethanol, and MTBE (answers must be received in that order) that must be present in gasoline to yield a mixture of 1.8 % oxygen by weight.
