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
