6. If a drug dose is 50 mcg how many doses are contained in 0.01 g?

Answer: C

Explanation:

200 doses are contained in 0.01 g.

To determine how many doses of 50 mcg are in 0.01 g, we first convert 0.01 g to micrograms, which equals 10,000 mcg. Dividing 10,000 mcg by the dose of 50 mcg gives us 200 doses.

A) 2

This option is incorrect because if there were only 2 doses of 50 mcg in 0.01 g, that would imply only 100 mcg in total. Since 0.01 g equals 10,000 mcg, this option significantly underestimates the number of doses.

B) 20

This option is also incorrect; 20 doses of 50 mcg would amount to 1,000 mcg. Since 0.01 g equals 10,000 mcg, this option still does not meet the total available amount.

C) 200

This is the correct answer. By converting 0.01 g to micrograms (10,000 mcg) and dividing by the dose size of 50 mcg, we find that there are indeed 200 doses (10,000 mcg ÷ 50 mcg = 200).

D) 2000

This option is incorrect because if there were 2000 doses of 50 mcg, the total would be 100,000 mcg. This exceeds the available amount of 10,000 mcg in 0.01 g, making this answer impossible.

Conclusion

The calculation confirms that 200 doses of 50 mcg can be derived from 0.01 g, which equals 10,000 mcg. All other options fail because they either underestimate or overestimate the total available dosage, demonstrating the importance of accurate unit conversion in dosage calculations.
