It takes 45.0 hours
to transport sodium-24 from the nuclear reactor where it is made to the
lab that uses the isotope. What is the minimum amount that must be
sent from the nuclear reactor for the lab to receive 2.00 grams if
sodium-24 has a half-life of 15.0 hours?
A.
4.00 g
The
half-life is the time necessary for half of the atoms to decay.
