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

8 capsules of clindamycin are required.

Step-by-step explanation:

Amount of clindamycin in 100 mL solution = 600 mg

Amount of clindamycin in 1 mL =
`(600 mg)/(100)=6 mg`

Amount of clindamycin in 200 mL solution :

`200* 6 mg=1200 mg`

Mass of 1 capsule = 150 mg

Number of capsules required to make 200 milliters of solution:

`(1200 mg)/(150 mg)=8`

8 capsules of clindamycin are required.
