The approach to determining the answer to this problem is to use the proper dimensional analysis. To determine the volume of the drug that should be administered, we divide the given mass in prescription by the concentration of drug.

V = (22 mg)/ (50.0 mg / 1.0 mL)

Simplifying,

V = 0.44 mL

Answer: 0.44 mL
