Answer:

80ml of the solution with a 50% acid concentration.

Step-by-step explanation:

Amount of acid in the water solution:

50ml * 20%= 10 ml

∴There is 10ml of acid in the solution.

Final amount of liquid:

50ml + 30ml = 80ml

Final amount of Acid:

10ml + 30ml = 40 ml

Concentration of Acid in Solution

40ml / 80ml = 0.5 = 50%

50 ml * 20% = 10 ml
50+30 =80
10+30 =40
40/80=50%
