One pair of students will prepare 50mL of a 0.11M solution of copper (II) chloride dihydrate (MW=170.5) and the other pair of students will prepare 50mL of a 0.26M solution of cobalt chloride hexahydrate (MW=237.9). | ||
#Calculate the correct weight of the material to yield 50mL of the proper molarity for the cupric or cobalt chloride solutions and record all calculations in your lab notebook. What would be the millimolar concentration of your solution? Have your lab instructor check your calculations before you weigh the material. | #Calculate the correct weight of the material to yield 50mL of the proper molarity for the cupric or cobalt chloride solutions and record all calculations in your lab notebook.
