How would you prepare 250 mL of a 0.150 M solution of CoCl2 from solid CoCl2 and distilled water? Be specific when you list the actions you would take.To prepare 250mL of a 0.150 M of solution of CoCl2 from solid CoCl2 and distilled water, the molarity would be the weight of solute(1000)/ gram molar mass (volume of solution in mL. The gram molar mass of CoCl2 is 130. 0.15= the weight of solute (1000)/130(250). The weight of the solute=0.15(130)(250)/1000=4.875gm. 4.875gm of CoCl2 dissolves in 250mL of solution to get 0.150M
