What volume of phenytoin suspension 30 mg/5 ml is required to be added to a suitable diluent to obtain 150 ml phenytoin suspension 20 mg/5 ml? 100

Explanation:

The given data is as follows.

Concentration of phenytoin suspension stock = 30 mg/5mL

Concentration of phenytoin required = 20 mg/5 mL

Volume of phenytoin required = 150 mL

Volume of phenytoin suspension stock required for dilution will be calculated as follows.

                  = 100 mL

Thus, we can conclude that the volume of phenytoin is 100 mL .
