Moles in physics

  1. Jun 14, 2012 #1
    1. The problem statement, all variables and given/known data
    What would be the mass of one hundred million million (100 000 000 000 000 = 1014) atoms of Uranium 238 (atomic mass is 238)?


    2. Relevant equations



    3. The attempt at a solution
    I tried finding the mass of each particle by diving the avogadro constant by 238.. The answer multiplies by 10^14.. However, this gives the wrong answer

    Hi ehabmozart!! :smile:

    Noo!!

    The mass of one mole(Avogadro number of molecules) is 238 grams , what is the mass of one molecule??

    In other words, the mass of 5 identical boxes is 10kg, what's the mass of each box? :wink:
