Question

How much mass-energy (in joules) is contained in a peanut weighing 0.14 ounces? How much mass-energy (in joules) do you gain by eating 14 ounces of peanuts? Compare this with the food energy content of peanuts, about 100 kcal per ounce. (Give your answer as a ratio of the mass-energy of peanuts per ounce to the food energy content of peanuts, where both values have the same units. Assume 1 kcal = 4,184 J.) mass-energy of peanuts per ounce food energy content of peanuts
