Answer:

By dissolving 0.002 mol of #CaCl_2# in 1 L of solution.

Explanation:

Molarity of a solution is the number of moles of the solute per litre of the solution.Hence a 0.002M solution means that 0.002 mol of solute is mixed in a litre of solution.The volume of solution can be changed but the ratio of moles to volume should remain same.
