3. A tank contains 400 liters of brine holding 300 kg of salt in solution. Water containing 125 g of salt p liter flows into the tank at the rate of 12 liters per minute, and the mixture kept uniform by stirring, flows out at the same rate. Find the among of salt at the end of 90 minutes. Hint: P = Pin'in - (+ dt Tout Vo+(rin-rout)t)
