Answer:
8 unit doses
Step-by-step explanation:
A 0.0417% concentration means that 100 mL of solution contains 0.0417 grams = 41.7 mg of the active ingredient.
Cross-multiplying
100 mL ------- 41.7 mg
x mL------- 10 mg
100/x = 41.7/10 --------> x = 1000/41.7 = 23.9808 = 24 mL rounding to the nearest integer.
As a unit dose of Levalbuterol HCL contains 3.0 mL,
we need 24/3 = 8 unit doses to obtain 10 mg of the active substance.
Surface area is 8.25(pi) or 25.9181
