    Hi, I have a question please . It's written H2S2O7 . The question says how many moles of atoms of oxygen.
    So the answer is written 7
    But I don’t understand why ?
    There are 7 atoms of Oxygen but why is the moles the same number as the atoms
    Isn’t any there any difference between
    **no of atoms**
    and
    **moles of atoms** ???
