theoretical percent sulfate in AlK(SO4)2*H2O

  • chemistry -

    Find the total molecular mass of it
    one Al, one K, two S, eight O, and one H2O


    divide that sum (the mole mass) into the mass of two SO4 ions.

  • chemistry -

    (2xmolarmass SO4/molar mass AlK(SO4)2.H2O)*100.

    Let me point out that alum is AlK(SO4)2.12H2O. I don't know if your problem is real or a typo. Just look at it to see.

  • chemistry -

    so it would be like 96.06g/258.33g?

  • chemistry -

    no it would be 192.14/258.33?

  • chemistry -

    The 192.14 is ok but I think you omitted the water in the 258. I think that is supposed to be something like 276 or so. Check it out.
