A hospital prepares a 100mg supply of technetium-99m which has a half-life of 6 hours. what is the decay factor?
SashulF [63]
For a half- life, the formula is
A(t) = A0(0.5)^( t / t_0.5)
where A(t) is the amount of substance at time t
A0 is the initial amount of subtance
t_0.5 is the time it will reduce its amount to half
t is the time

substitute the given to the formula
A(t) = 100(0.5)^( t/6 )
so the decay factor is 0.5^( t/6 )

erica [24]

Without so much as a quick peek at the picture, it's not possible to even begin
to answer the question.  That's the reason, you see, that the picture is printed
right there, along with the question, in the same place from which you copied
this cut-off portion of the question.  It's not enough.  We need the picture too.
