Situation: Find the substance's half-life, in days.
Round your answer to the nearest tenth.
A 10 gram sample of a substance that's
used to detect explosives has a k-value
of 0.1356.
Enter the correct answer.
N = Noe
-kt
DONE
No = initial mass (at time t = 0)
?
N = mass at time t
k = a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days
