Question 258822: A photographer is mixing 5% acetic acid solution with a 10% acetic acid solution to get 2 liters of a 7% solution. How many liters of each solution should he add? Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! F-liters of 5% solution
T-liters of 10% solution
1.Volume equation:
2.Concentration equation:
Use eq. 1 to solve for F in terms of T and substitute into eq.2,
2.
Then from eq. 1,
Use 4/5 liter of 5% solution and 6/5 liter of 10% solution.
