how mant moles are in 1.30g of (NH4)2SO4?
answer in units of mol.

today our teacher briefly went over this and doing my homework i totally lost it. and cant remember for the life of me what to do could you please help me and show me step by step what to do.
thanks

  • Chemistry -

    determine the mole mass of ammonium sulfate.

    add the atomic masses of each of the constituents.

    Constiutents are 2N, 8H, 1S, 4O
    look up the atomic masses of N, H, S, and O, and then multiply each by the coefficent. I get a little over 132grams. YOu do it accurately.

    Then finally, divide that into 1.30grams
