Q. A teaching assistant at a university needs acid solution for her class's lab experiment. There isn't any of this concentration in stock, but the lab has liters of acid solution, as well as a lot of acid solution. How much of the acid solution should the teaching assistant add to the acid solution to obtain a solution with the desired concentration? Write your answer as a whole number or as a decimal rounded to the nearest tenth.____ liters
- Denote Acid Solution Volume: Let's denote the amount of acid solution that needs to be added as liters. The total volume of the new solution will be liters + liters.
- Calculate Pure Acid in % Solution: The amount of pure acid in the liters of solution is liters.Calculation: liters of pure acid.
- Calculate Pure Acid in % Solution: The amount of pure acid in the liters of solution is liters.Calculation: liters of pure acid.
- Calculate Total Pure Acid: The total amount of pure acid in the final solution should be of the total volume, which is of liters.Calculation: liters of pure acid.
- Set Up Equation: To find the value of , we set up the equation that the sum of the pure acid from both solutions equals the pure acid in the final solution: .
- Solve for x: Now we solve for x:,,, liters.
