Define the half life of radioactive cobalt

Reference no: EM13715943

Question- The half life of radioactive cobalt is 5.27 years. if 200 grams of radioactive cobalt is present now, when will only 20 grams be present?

Anyone can tell me how to solve it step by step so that I will be able to understand what is going on?
