dissolved in enough water to make 763
milliliters of solution, what is the molarity of sulfate ions?
Answer in units of M.

  • Chemistry PLEASE HELP! -

    I wonder what is going on here? this is incredibly easy

    Moles sulfate ions in Al2(SO4)3
    Molarity= molessulfateions/liters of solution
    = 3*.042/.763 moles/liter
