How many moles of bromine atoms are in 8.0x10^20 bromine molecules?

  • Chemistry -

    1 mole = 6.02x10^23
    A bromine molecule has the formula Br2.
    Multiply the number of Br2 molecules by 2 to get the number of atoms of bromine.
    Divide the number of atoms by 6.02x10^23 atoms/mole to get moles of Br atoms
