Question

Ketamine sometimes used as an adjuvant to general anesthesia, is available as a 10.0%(w/v) solution. Calculate the mass of ketamine in 2.50 ml of this solution.

Answer 1

0.25 grams

Step-by-step explanation:

mass = (concentration x volume) / 100

The concentration of ketamine is 10.0%w/v and the volume is 2.50 ml.

mass = (10 x 2.50) / 100

mass = 0.25 g

So, there is 0.25 grams of ketamine in 2.50 ml of a 10.0% (w/v) solution.
