    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%
