I need to find out Molar solubility of CuS. How many grams of CuS are present in 15.0 L of a saturated CuS solution,

  • chemistry -

    ...............CuS ==> Cu^2+ +S^2-
    equilibrium..............x.....x

    Ksp = (Cu^2+)(S^2-)
    Ksp = (x)(x)
    Solve for x which gives you the molar solubility (that's moles/L)
    grams/L = moles x molar mass
    Then you want grams/15 L so multiply by 15.
