little confused why the book is saying 20 mL and not 2 mL ... is it bc you use the 10 mL multiple dose vial after you solve

Answer 1

Solution: It is given that Vial contains 4mg per ml of the drug.

So, 8 mg of drug will be required = 8/4 = 2ml.

( The answer is 2.0mL)

Solution: for 6mg the mL required will be 6/4 = 1.5 mL

Solution: 40mg of the drug content present in 10ml

So, 20mg of drug will be present = 20× 10 = 200

200÷ 40 = 5mL.
