I'm stuck in the question solve this question quickly

(b) The half-life of Cobalt 60, used in food irradiation, is 5.27 years. Assume that this radio-active isotope decays according to the model: A(t) = Age -kt where Ao is the initial mass and & is the decay constant. (i) Calculate the decay constant & for Cobalt 60. (ii) Calculate the time required for the mass of Cobalt 60 to be reduced to 10 grams, if the initial mass was 50 grams
