Kindly refer to the attached picture. 

Calculate the number of pounds of CO, released into the atmosphere when a 20.0 gallon tank of gasoline is burned in an automobile engine. Assume that gasoline is primarily octane, C,H1g, and that the density of gasoline is 0.692 g · mL-!. This assumption ignores additives. Also, assume complete combustion. CO, released: Ib

Expert Solution
Step 1


Given that density of gasoline = 0.692 g/ mL that means  the mass of 1 mL of gasoline is 0.692 grams.

Also given volume of gasoline = 20.0 gallon 

1 gallon of gasoline = 4546.09 mL of  gasoline  

therefore, 20.0 gallon of gasoline = 20*4546.09 = 90921.8 mL of  gasoline  

20.0 gallon of gasoline = 90.9 L of  gasoline

At STP conditions, 1.0 mol of gasoline = 22.4 liters of gasoline

therefore, 90.9 liters of gasoline = 90.9/22.4 = 4.059 mol of gasoline
