Question

A pharmacist added 50 g of drug to make a total of 200 mL of solution. What is the percentage of drug in the resultant solution?

Answer 1

Answer:

The percentage of drug in the resultant solution is 25% .

Step-by-step explanation:

Given :A pharmacist added 50 g of drug to make a total of 200 mL of solution.

To Find : What is the percentage of drug in the resultant solution?

Solution:

Amount of drug = 50 g

Amount of solution = 200 ml

So, the percentage of drug in the resultant solution = $\frac{\text{Amount of drug}}{\text{Amount of solution}} \times 100$

                                                                                       = $\frac{50}{200} \times 100$

                                                                                       = $25\%$

Hence The percentage of drug in the resultant solution is 25% .
