Prepare 250mL of 2.00M CuSO4 from CuSO4 x 5H2O

  • chemistry -

    You want how many moles of CuSO4?
    M x L = moles = 2.000 x 0.250 L = ??

    How many grams CuSO4 is that?
    moles = grams/molar mass and solve for grams CuSO4 = xx grams CuSO4.

    BUT you don't have CuSO4. You have CuSO4.5H2O so convert xx g CuSO4 to zz grams CuSO4.5H2O.
    That will be done easily by
    [xx g CuSO4 x (molar mass CuSO4.5H2O/molar mass CuSO4)] = ?? and weigh out that many grams of CuSO4.5H2O. Place in a 250 mL volumetric flask, add enough water to dissolve all of the solid, add water to the mark, shake until the solution is thoroughly mixed.
