A student is instructed to determine the concentration of an unknown solution of CoCl2 found in the stock room. The student decides to measure its absorption of light (spectrometric/colorimetric method) to calculate the concentration. The student is provided with solid CoCl2, a balance (0.001g precision), weighing paper, a spatula, a 100mL volumetric flask, distilled water, and a glass stirring rod. Describe the procedure for making a 100mL solution of CoCl2 with a concentration of 0.10M. Include specific amounts and calculations where appropriate?
