1. The half-life of Plutonium-239 is 24,100 years. 10 grams of Plutonium-239 were released in a nuclear accident. How long will it take for the 10 grams to decay to 1 gram? 2. A tank with 100 liters of brine containing 50 kg of dissolved salt. Pure water is allowed to run into the tank at the rate of 3 liters per minute. Brine runs out of the tank at the rate of 2 liters per minute. The instantaneous concentration in the tank is kept uniform by stirring. How much salt is in the tank at the end of one hour?
