Answer: 25%
Step-by-step explanation:
Given : A pharmacist added 50 g of drug to make a total of 200 mL of solution.
Here, Resultant solution = 200 mL
Amount of drug = 50 g
We know that 1 gram = 1 ml
So, we can say the amount of drug = 50 ml
Now, the percentage of drug in the resultant solution:-
Hence, the percentage of drug in the resultant solution= 25%
