How many moles of silver atoms are in 2.8 x 10^20 of silver?

  • chemistry -

    recall that one mole of any substance is equal to Avogadro's number, which is
    6.02 x 10^23
    this number can be atoms, molecules, ions, etc.
    to get the number of moles, we just divide the given by the Avogadro's number:
    2.8 x 10^20 / 6.02 x 10^23 = ?

  • chemistry -

    4.65x10^-4mol
