Question 14 • Now, change the solute to cobalt(II) chloride, and change from the 'solid' shaker to the 'solution' dropper.
. Make sure you are starting with 1/2 L of water in your container.
• Add the CoCl2 solution by clicking on the red dot on the dropper.
• Add the cobalt(II) chloride solution until you reach a total volume of 1 L (it will automatically stop adding
once you reach 1 L, so don't worry about going over).
Use the concentration meter to determine the concentration of the solution.
If you added 0.5 L (V1) of the cobalt chloride solution, to a final volume (V2) of 1 L, and a molar concentration
of
(M2), the original concentration of the cobalt(II) chloride solution must have been
(M1).
