Answer:
Answer: 12 milliliters
Step-by-step explanation:
Proportions
Each vial contains 250 milligrams of aminophylline in 10 milliliters. This means the concentration of aminophylline in the vials is 250/10 = 25 milligrams/milliliter.
To administer 300 milligrams of aminophylline, we need to find the number of milliliters according to the concentration calculated above.
If each milliliter adds up to 25 milligrams, then to have 300 milligrams, 300/25 = 12 milliliters of aminophylline vials are needed.
