Develop a method to prepare 100 ml of 0.500mol/l aqueous CuSO4x5H2O solution. Include the water molecules that are hydrated to the crystals as given in the molecular formula, in your calculation of the molar mass. show all your calculations. Prepare the solution.

Answer 1

I don't know about this being a method; it is a procedure for doing the job.
How many mols do you want? That's M x L = ?
Then mols = grams CuSO4*5H2O/molar mass CuSO4*5H2O = ?.
Place that many grams CuSO4*5H2O in a 100 mL volumetric flask, add some water, swirl until dissolved, then fill to the mark on the volumetric flask with distilled or deionized water. Mix thoroughly. stopper.
