Answer:
0.5ml
Explanation:
Step-by-step explanation:
The dose of the medication must be equal to 10mg, and we know that the vials contain 20mg/ml
This means that in each milliliter of the solution, we have 20mg of the medication, but we only want to give 10mg, so we must use half of a milliliter.
you can also calculate this by:
Amount needed/amount of the medicament in volume
10mg/(20mg/ml) = (1/2) ml = 0.5ml
