Estimate gasoline consumption A. Using your own judgment, estimate the gallons of gasoline consumed in Norman, OK (100,000 people). State your assumptions. B. From this number, extrapolate your estimation to the gasoline consumption in the entire country (US ~ 350 million people). After getting this number, look up the US annual gasoline consumption on the web site of the Energy Information Administration. Compare this number to your estimate and comment on the differences.

If biomass is converted to ethanol, how much biomass is required annually to meet the needs of US annual gasoline consumption reported by EIA? State your assumptions. Be sure to account for the difference in energy content of ethanol vs. gasoline. B. If biomass is converted to true gasoline (approximate chemical formula C7.1H12) how much biomass is required annually to meet the needs of US annual gasoline consumption? State your assumptions. Discuss the advantages and disadvantages of cases A and B. _____________________________________________________________________________________________________ 3. Commodity Chemicals A.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
