A chemist takes 22.1 mL of a solution containing dissolved copper at a concentration of 31 mg of copper per mL of solution. The chemist then initiates a reaction in the solution that causes all of the copper to form a precipitate (form a solid) that settles to the bottom of the container. What should be the mass (in grams) of the copper precipitate?
