Suppose the car (van, SUV) you drive gets 25 miles/gallon. If you drive 19,000 miles per year how many tons of the green house gas CO2 are you releasing each year? Assume your fuel is octane (C8H18) and the combustion reaction is balanced: C8H18 + 12.5 O2 → 8 CO2 + 9 H2O Addition information: Density of octane = 0.700 g/mL 1 gallon = 3785 mL 1 pound = 454 g 1 ton = 2000 lbs

1. Assuming your car gets 30 miles/gallon and you drive 5,000 miles each year, calculate how many gallons of gasoline you use per year by driving your car. Give your (numerical) answer to the nearest 1 without any unit. 2. )Using your answer above, 167 gallons, calculate how many liters of gasoline your car burns per year. 1 gallon = 3.8 liters, 1 L = 1000 mL, 1 kg = 1000 g Give you answer to the nearest 1 without...

Calculate the volume of CO2 produced at 1 atm and 20.0 C from the complete combustion of 1.00L of gasoline. Although gasoline is a mixture of hydrocarbons, for the purposes of this calculation consider gasoline to have the same chemical formula C8H18 and the same density as n-octane: 0.702 g/mL. Calculate the volume of CO2 produced by driving 100 miles on the highway in a mid-sized sedan compared to an SUV, given their highway efficiencies of 33 mpg and 19...

1. a. The car I drive is a Toyota Prius C; its average mileage rating is 52.0 mpg. Convert this rating into units of kilometers traveled per liter of gasoline consumed. (3 pts) b. Gasoline is a mixture of several hydrocarbon compounds, but let's assume that it consists of only one: octane. If the density of octane is 0.703 g/mL, use the result from part a to calculate how many kilometers the Prius C can travel on one kilogram of...
