Situation: A 25 gram sample of a substance thats used for to sterilize surgircal instruments has a k-value of 0.1205. 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.
