How much quantity of sodium chloride is needed to make 30 ml of a 2% isotonic drug (sodium chloride equivalent 0.20) solution?
A. 0.60
B. 0.15
C. 0.27
D. 0.12

    I don't understand the question. A 2% isotonic solution seems to be an oxymoron to me. An isotonic solution is about 0.9% NaCl/100 mL solution.
