Situation:
a 30 gram sample of a substance thats used for to sterilize surgircal instruments has a k-value of 0.1253.
n=noe^-kt
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 substance's half-life, in days. round your answer to the nearest tenth.
