Question 1162876: After 20 minutes, an initial sample of 192 grams of a radioactive element decays to 6 grams. Determine the half-life of the element.
this is a grade 11 function, i just want to know how to answer it with the equations and how to solve. Found 2 solutions by Boreal, ikleyn:Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! P=Po(1/2)^t
P/Po=(1/2)^t
6/192=(1/32)=(1/2)^t
log 2 of both sides
-5=t(-1)
t=5 half-lives and that was over 20 minutes. The half-life is 4 minutes

~~~~~~~~~~~~~~~~
= 32 = .
5 half lives in 20 minutes.
One half-life period is = 4 minutes.
