Mass Energy Relationship
1 kg of gasoline when burned in oxygen will give off about 4 x 10^7 joules of heat. According to Einstein any mass has an equivalent energy of E = mc^2. How  many  kgs of gasoline would have to burn ( with oxygen) to make the same amount of energy that Einsteins theory predicts that a single kg is equivalent to?
