Answer:
10 liters.
Step-by-step explanation:
Let the volume of 2% acid be x liters.
Then the volume of the 8% solution will be (x + 30) liters.
Work in amounts of pure acid: amount of acid in the 10% solution = 30 * 0.1
= 3. So we have the equation:
0.02x + 3 = 0.08(x + 30)
0.08x - 0.02x = 3 - 0.08*30
0.06x = 0.6
x = 10
So the answer is 10 liter of the 2% solution.
