1364 mg
none are correct
16.5 mg
6600 mg
3.4 mg
question 2 (1 point)
if a patient is to receive 5 g of a liquid drug and the drugs density is 0.85 g/ml, how many ml of the drug would the patient take?
2.5 ml
4.25 ml
5.88 ml
15 ml
5 ml

Explanation:

Step1: Convert pounds to kilograms

1 pound = 0.453592 kg, so 150 pounds = 150×0.453592 = 68.0388 kg

Step2: Calculate drug dosage

Dosage is 20mg/kg, so for a 68.0388 - kg person, the dosage is 20×68.0388 = 1360.776 mg ≈ 1364 mg

Step3: Solve for volume in Question 2

Use the density formula $
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass and $V$ is volume. Rearranging for $V$ gives $V = \frac{m}{
ho}$. Given $m = 5g$ and $
ho=0.85g/ml$, then $V=\frac{5}{0.85}\approx5.88ml$

Answer:

Question 1: 1364 mg
Question 2: 5.88 ml
