Homework Help: Tank filled with a solution

  1. Nov 8, 2016 #1
    1. The problem statement, all variables and given/known d
    Let's say there's a tank filled with a solution to its maximum volume V. Initially, the solution in V is water mixed with some amount of salt S. The objective is to add more of a solution also consisting of water and salt such that the amount of salt S is the same after the added solution is in the tank. Note: because the tank is filled to its maximum volume, as the solution is added, water of the same volume escapes from the tank.

    How would you go about solving this?
    2. Relevant equations
    None, I confess I am stumped.

    3. The attempt at a solution
    See above.

    "water of the same volume escapes from the tank", or "an equivalent amount of the current solution escapes from the tank" ?

    Are you sure you are stating the problem correctly? Do you understand why those two problem statements are radically different?
