is left in a sample after 288 hrs then how much P-32 was administered initially? [The
half-life of P-32 is 14.3 days.]
6.26 mg
4.17 mg
1.96 mg
7 mg

Respuesta :

Answer:

6.26mg

Step-by-step explanation:

288hrs divided by 24hrs is 12 days... so that means it didnt complete its half life... so your answer should be a little less than double the leftovers

6.26 mg! that’s the answer!! hope it helps you.
