Plutonium decays at a rate which is proportional to quantity available with us. In the lab conditions, it was observed that 50 kilograms of plutonium has lost its 10 percent of its original mass after a period of 2 hours. Find (a) the plutonium mass that will be present after 4 hours, and (b) Estimate the time required for plutonium to decay to one half of its initial mass.
