A copper stock solution has been prepared for you as follows. Weigh 0.1000 g of copper,
after cleaning with CCl4. Dissolve it in a slight excess of 8 M nitric acid, dilute four times
with deionized water, boil to remove nitrogen oxides and dilute to 1 litre in a volumetric
flask.

What is the concentration of the standard that is prepared by transferring 5.0 mL of the dilute copper stock to a 500 mL volumetric flask?
