The formula to calculate the mass, M(t), remaining from an original sample of radioactive material with initial mass Mo, is determined using the M(t) = Mo 1 (9) I where t is time and h is the half-life of the substance. Example: Suppose that a shipment of 200 g of radioactive radon was sent to a lab. After 16 days, only 12.5 g of the radon remained. Determine the half-life of radon.
