Question #47f0f

Answer 1

B.

Explanation:

If the final mixture has to contain 150 mg/ml of penicillin,that means 150 mg of penicillin will be present in 1 ml of solution not 1 ml of sterile water.

Given, 600 mg of penicillin was present in the container,so volume of the solution becomes (600/150)ml or 4 ml

Now,3.6 ml of this 4 ml is sterile water(as given)

so,volume of penicillin in this solution is (4-3.6)ml or 0.4ml
