If the rate of an isotope in 18 days has dropped by one eight of its initial value. what is the half life of the isotope?
My answer
In 18 days the rate has dropped by 1/8 so therefore the half life is 4/8 which is 18*4 = 72days
My answer
In 18 days the rate has dropped by 1/8 so therefore the half life is 4/8 which is 18*4 = 72days
