Answer:
5:3
Step-by-step explanation:
Given that the chemist mixed 5 mL of Solution A with every 3 mL of Solution B to make a new solution with a new concentration.
So, the amount of Solution A in the mixture, a = 5 mL
The amount of Solution B in the mixture, b = 3 mL
Therefore, the ratio of Solution A to Solution B in the new solution with the same concentration is a:b=5:3.
Hence, the required ratio for the same concentration is 5:3.
