caculate the number of moles in 8200 g of iron

  • chemistry -

    moles = grams/molar mass

  • chemistry -

    can u show me how to set it up because i don't get it at all

  • chemistry -

    What is there to get.
    moles = grams/molar mass.
    g is given to you (8200 g).
    molar mass of Fe you obtain from the periodic table. Look it up. I think it's about 55 or something like that.
    And you divide one number by another. Don't try to make this harder than it is. If you can divide 4/2 you can do this.
