![]() The amount of solute in the solution (n) = concentration (c initial) × volume (V initial) V initial = the initial volume of undiluted solution = 5 mLĬ initial = ? (we have not been told the concentration of this solution) Remember, dilution factor tells us the ratio of the initial (undiluted) volume of solution to the final (diluted) volume of solution:Īnd, concentration in moles per litre (c)Ĭ = amount of solute in solution (n) ÷ total volume of solution (V)Ĭonsider a 250 mL volumetric flask containing ONLY a 5 mL aliquot of a solution with a concentration of c initial (this will look like a thin layer of solution in the bottom of the otherwise empty flask). Play the game now! Effect of Dilution Factor on Concentration What it means is, take a known volume of the stock solution (V initial) and add enough solvent to it so that the solution has a new volume, V final, of 50 x V initial. You may come across something like, "prepare a 1:50 dilution of the solution". No ads = no money for us = no free stuff for you! Definition of Dilution Factor A dilution factor, DF, can be calculated:. ![]()
