calculate the density in g/ml of 4.0 l of gasoline that weighs 1.25kg
When 1.0 g of gasoline burns, it releases 11 kcal of heat. The density of gasoline is 0.74 g/mL. Part A How many megajoules are released when 4.0 gal of gasoline burns? Part B If a television requires 150 kJ/h to run, how many hours can the television run on the energy provided by 4.0 gal of gasoline? Can someone explain on paper how they got their answer... Its confusing.
