How many megajoules are released when 9.0 gal of gasoline burns.
how do I start to do this problem, and what are the steps to get there.
1. Write and balance the equation.
2. Use density gasoline to convert 9.0 gallons to grams.
3. Look up the heat of combustion or calculate it from the delta H formation values.
4. heat combustion x (grams gasoline/molar mass gasoline).
Post your work or supply details (numbers) if you run into trouble.
