Explain the difference between an average and a weighted average
4. Gasoline can be reasonably approximated as C9H20 with a density of 0.718 g/mL. Diesel can be reasonable approximated as C14H30 with a density of 0.763 g/mL. (Both gasoline and diesel are complicated mixtures. These formulas are something like weighted averages of the formulas of the different components, where the weighting is based on various quantifiable behaviors. That is, using these artificial formulas for gasoline and diesel allows one to calculate average properties that match what petroleum engineers might measure.) The enthalpy change from burning one mole of gasoline is -6160 kJ. The enthalpy change from burning one mole of diesel is -7940 kJ. Determine which fuel generates the biggest enthalpy change per gram burned, and which generates the biggest enthalpy change per mL burned.
