Do I need to have the density of gasoline to figure this problem. Since grams

is mass and gallons is volume? ? The average LCD TV uses 176 watts of power. If we get 11.3 kcal of heat from combusting 1.00 g gasoline, how Many gallons are required to run an LCD TV for 1 year if it is on 3 hours a day?

Hints: 176 watts used for 1 hour = 176 Wh = 0.176 kWh
A kWh is a kilowatt-hour
1 kWh = 3600kJ
I am stuck on this problem. I was told the only way to convert b/t mass and volume is through density. I do not know the density for gasoline. If I can solve this problem w/o density, could you please point me in the right direction. Maybe some conversion factors.
