2. A teaching assistant at a university needs 28% acid solution for her class's lab experiment. There isn't any of this concentration in stock, but the lab has 50 liters of 22% acid solution, as well as a lot of 32% acid solution. How much of the 32% acid solution should the teaching assistant add to the 22% acid solution to obtain a solution with the desired concentration?
