Question

2 pts Question 2 Calculate the number of mL of penicillin a 27.0 lb child would take if the recommended dosage is 1.50 mL per kg. Note, 1 kg = 2.2046 lb. Use the correct number of significant figures at each step. 2 pts D Question 3 Pressure (psi) vs. Height (miles)

Answer 1

The number is
`18.371 mL` of penicillin

Step-by-step 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 :

`27.0lb.(1kg)/(2.2046lb)=12.247kg`

The child weight is 12.247 kg

Now we calculate the dosage for that weight

Dosage = Recommended dosage x Child weight

`Dosage=(1.50(mL)/(kg)).(12.247kg)`

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
