c) 50 mL

d) 75 mL

Answer 1

To fill the order for Amikacin 3% solution with a stock solution of Amikacin 12%, 25 mL of diluent should be added.

Step-by-step explanation:

To determine how much diluent should be added to the amikacin 3% solution, we can use the formula:

(% of stock solution)(volume of stock solution) = (% of final solution)(final volume)

Let's solve for the diluent volume:

(12%)(V1) = (3%)(100 mL)

V1 = (3%)(100 mL) / (12%)

V1 = 25 mL

Therefore, 25 mL of diluent should be added to the amikacin 3% solution to fill the order.
