Please Help me Nuclear Fission Problem

  1. Feb 2, 2007 #1
    Hi, I am studying in 10th Standard and preparing for final exams,
    anyone please help for this following question.

    When Uranium undergoes Nuclear Fission, 0.1 %(percentage) of total mass is converted into energy. Calculate tota amount of energy in Joules during an explosion of atom bomb which contains 5kg of Uranium.

    Please help me with the above question with steps, I will be very thankful to you all.

    It looks like you need to convert 5 grams of matter to energy, using E=mc2. You need a conversion table, which might give you grams to joules conversion directly.
