Question

An acne preparation contains 600 milligrams of clindamycin in 100 milliliters of solution. How many 150 milligram capsules will it take to make 200 mil liters of solution?

Answer 1

Answer:

8 capsules of clindamycin are required.

Explanation:

Amount of clindamycin in 100 mL solution = 600 mg

Amount of clindamycin in 1 mL = $\frac{600 mg}{100}=6 mg$

Amount of clindamycin in 200 mL solution :

$200\times 6 mg=1200 mg$

Mass of 1 capsule = 150 mg

Number of capsules required to make 200 milliters of solution:

$\frac{1200 mg}{150 mg}=8$

8 capsules of clindamycin are required.
