Calculate the number of grams in the following :[149.096 g/mole]

8.55 moles of (NH4)3PO4


IT WOULD BE NICE IF I CAN GET STEP BY STEPS TO GET ANSWER !!!

    First add up the molarity of your compound

    3N= 42.0201
    12H = 12.09528
    P= 30.97376
    4O = 63.99600

    Add those number up and you should get 149.08 (I rounded).

    (8.55mole) * (149.09g/1mole) = ??

    Dang it! I did not know what the :[149.096 g/mole] meant until I looked back again. Apparently they gave your the total mass of the compound! I went through and did all that work for nothing!

    Anyways your answer should not be off by much, but if you it to be as accurate as the problem says than use replace the grams

    Also, you are not adding up the molarity of the compound. Molarity is numer of moles of solute per liter of solution.
