Situation:
a 14 gram sample of a substance that's
used to sterilize surgical instruments has
a k-value of 0.1481.
n= noekt
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

find the half-life, in days. round your answer to the nearest tenth
