(a) 1.0gal * 3785mL/gal * 0.74g/mL * 11kcal/g * 4.184kJ/kcal = ___ kJ
(b) divide the kJ from (a) by 150 to get hours
If you watch the units, the conversions will take care of themselves.
When 1.0g of gasoline burns, it releases 11 kcal. The density of gasoline is 0.74 g/mL.
a. How many megajoules are released when 1.0 gal of gasoline burns?
b. If a television requires 150 kJ/h to run, how many hours can the television run on the energy provided by 1.0 gal of gasoline?
Can someone please show me how to solve this problem? I have no idea how to even begin.
