Question

How much diluent do you need to add to a 2 gm vial of Rocephin to get a concentration of 250 mg/ml? Disregard the space the powder may occupy.

Answer 1

Answer:

The volume of diluent = 8_ml

Explanation:

Required concentration = 250mg/ml

Quantity of solute = 2_g

Concentration of Solution = (Mass of solute)÷(volume of solvent)

Therefore, volume of solvent = (Mass of solute)÷ (Concentration of Solution)

= 2_g/(250_mg/ml) =2_g/(0.250_g/ml) = 8_ml

Therefore the volume of diluent = 8_ml
