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%
