Question

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 any unit.

3.) Using your answer above, 635 liters, calculate how many kilograms of gasoline your car burns per year.

Density of gasoline = 0.692 g/mL = 0.692 kg/L  

Give your answer to the nearest 1 without any unit.

4.) Gasoline is a complex mixture, comprised mostly of hydrocarbons. Octane (C₈H₁₈) can be used as a simple chemical model for gasoline. Thus the combustion of gasoline can be represented as:

2 C8H18 + 25O2 -> 16 CO2 +18 H2O

Using your answer above, 439 kg of gasoline, calculate(estimate) how many kilograms of CO₂ are produced by your car each year.

Give your answer to the nearest 1 without any unit.
