The specific activity of a preparation consisting of radioactive Co58 and nonradioactive Co59 is equal to 2.2⋅1012 dis/(s ⋅ g). The half life of Co58 is 71/3 days. Find the ratio of the mass of radioactive cobalt in that preparation to the total mass of the preparation (in per cent).

We see that Specific activity of the sample =M+M′1 [ Activity of Mgm of Co58 in the sample]
Here M and M′ are the masses of Co58 and Co59 in the sample. Now activity of Mgm of Co58
