An article states that the fission of 2.0 g of uranium-235 releases 6.8 * 108 kcal, the same amount of energy as burning two tons (4,000 lb) of coal. If this report is accurate, how much energy is released when 1.0 g of coal is burned?

    340 kcal

    Explanation:

    Energy released by 2 g of Uranium is same as the energy released by 2 tons of coal.

    Energy given by 2 tons of coal = 6.8 x 10^8 kcal

    Energy given by 2 x 10^6 g of coal = 6.8 x 10^8 kcal

    Energy released by 1 g of coal = (6.8 x 10^8) / (2 x 10^6) = 340 kcal
