Answer 2

c) (w/V)% is commonly used in pharmacies.

• Whenever we try to expression the concentration of a drug, there are various units in which we can do.

• For example, we can use Molarity, Molality, w/V , V/V , ppm, etc.

• However, in the medical field and in pharmacies, the most commonly used concentration unit is weight/volume (i.e. w/V).

For example : if a drug concentration is 10% (w/V), it means :

• 10 gram of drug is present in 100 mL of solution.
