Copper-64 is used in the form of copper acetate to study brain tumors. It has a half-life of 12.8 hours. If you begin with 15.0 mg of 64 Cu-labelled copper acetate, what mass in mg remains after 2 days and 16 hours?

Answer:

0.58 milligrams

Step-by-step explanation:

If this isnt correct than I appologize.

Just half of the power of tt makes up 60 hours. Then it is divided by t half knowing that there is 12.8 hours left. Then if you calculate it we get 0.58 mg and so after the 2 days and 16 hours we get our answer.
