Use the fact that the quantity of a radioactive substance after t years is given by g = go(2-t/k), where qo is the original amount of radioactive material and k is its half-life (the number of years it takes for half the radioactive substance to decay). The half-life of strontium-90 is 25 years. Find the amount of strontium-90 remaining after 15 years if qo = 102 kg. (Round your answer to the nearest kg.) kg
