Calculate the number of capsules needed:
Number of capsules = Ordered dose (mg) / Strength per capsule (mg)
Number of capsules = 15 mg / 15 mg/capsule = 1 capsule
Correct Answer is ["300"]
Explanation
Identify the Given Dose:
The prescribed dose is 0.3 grams (g).
Convert Grams to Milligrams:
We need to convert grams (g) to milligrams (mg) because medication dosages are often expressed in milligrams.
There are 1000 milligrams in 1 gram (1 g = 1000 mg).
0.3 g x 1000 mg/g = 300 mg
