USE THE VALUES GIVEN BELOW THE PROBLEM

A tank initially contains 200 gallons of water in which 50 lbs of salt are dissolved. A salt solution containing 0.5 lb of salt per gallon is poured into the tank at a rate of 1 gal/min. The mixture in the tank is stirred and drained off at the rate of 2 gal/min. a) Find the amount of salt in the tank until the tank is empty. b) Find the concentration of salt in the tank until the tank is empty. Where: x (t) = amount of substance dissolve in the solution at any time t ri = container SHOW FBD flow rate of the solution coming in the C₁ = concentration of the solution coming into the container dx dt ro = flow rate of the solution coming out from the container Co = concentration of the solution coming out from the container || r¡Ci - roCo
