Explanation:

Question 3

Step1: Identify total and per tablet

Total drug needed: $1500$ mg, per tablet: $500$ mg.

Step2: Calculate tablets

Tablets = $\frac{1500}{500}$ = $3$

Step1: Convert grams to milligrams

$0.3$ g = $0.3\times1000 = 300$ mg.

Step2: Find mL per mg

Drug on hand: $75$ mg/10 mL, so per mg: $\frac{10}{75}$ mL/mg.

Step3: Calculate total mL

Total mL = $300\times\frac{10}{75}$ = $40$

Step1: Convert grams to milligrams

$0.72$ g = $0.72\times1000 = 720$ mg.

Step2: Calculate capsules

Capsules = $\frac{720}{120}$ = $6$
