Answer:
The number is [tex]18.371 mL[/tex] of penicillin
Explanation:
This is a unit conversion problem.
The dosage for the child will be the recommended dosage multiply by the child weight
Let's calculate the child's weight :
[tex]27.0lb.\frac{1kg}{2.2046lb}=12.247kg[/tex]
The child weight is 12.247 kg
Now we calculate the dosage for that weight
Dosage = Recommended dosage x Child weight
[tex]Dosage=(1.50\frac{mL}{kg}).(12.247kg)[/tex]
Dosage = 18.371 mL
We must be careful with the units.
The recommended dosage is in mL/kg units and the child weight is in kg units
