Complete the following table. The only density needed is already given. Show your
calculations in a neat and easy-to-follow manner in the space below the table. All units
should be included and significant figures should be given close attention. Be sure to notice
that the amount of material should be in millimoles rather than moles, and the theoretical
mass of the product should in milligrams rather than grams.
