  1. Calculate the RMM (relative molar mass) for NiCl2.6H20

    Mass required for one litre of 0.5M solution = 0.5*237.64= 118.82 g

    Fill a 1 litre volumetric flask with about 800 ml of distilled water and gradually introduce the crystalline nickel chloride inside the flask. Swirl the liquid to facilitate solution.

    Fill the flask to about 25mm below the mark, close the stopper and homogenize the solution. Finally, fill up to the mark and homogenize again.
