Calculate the number of pounds of co2 released into the atmosphere when a 22.0 gallon tank of gasoline is burned in an automobile engine. assume that gasoline is primarily octane, c8h18, and that the density of gasoline is 0.692 g⋅ml^−1. this assumption ignores additives. also, assume complete combustion. co2 released:

391.28771 pounds of carbon-dioxide released into the atmosphere.

Explanation:

Density of the gasoline ,d= 0.692 g/mL

Volume of gasoline in an tanks,V = 22.0 gallons = 83,279.02 mL

Let mass of the gasolin be M

M = V × d = 83,279.02 mL × 0.692 g/mL=57,629.081 g

Assume that gasoline is primarily octane (given)

Mass of octane burnt in the tank =  M = 57,629.081 g

Moles of octane =

According to reaction, 2 moles of octane gives 16 moles of carbon-dioxide.

Then 505.1637 mol of octane will give:

of carbon-dioxide

Mass of 4,041.3100 mol of carbon-dioxide:

4,041.3100 mol × 44.01 g/mol = 177,858.05 g

Mass of carbon-dioxide produced in pounds = 391.28771 pounds

391.28771 pounds of carbon-dioxide released into the atmosphe
