2. Use V1M1 = V2M2 to calculate the new concentration after . the dilution. Model. What is the new concentration when 75 mL of water are added to 125 mL of a 1. 00 M C6H12O6 solution? Given Find volume of water added = 75 mL. V1 = 125 mL. M1 = 1. 00 M V2 = ? M2 = ? V2 = V1 + volume added. V2 = 125 mL + 75 mL = 200. mL. V1M1 = V2M2 (125 mL)(1 ...

Dilution Calculations. Standard solutions used for making calibration curves are often prepared by diluted a more concentrated stock solution. A known volume of the stock solution is transferred to a new container and brought to a new volume. Since the total amount of solute is the same before and after dilution, we know that:

C1V1 = C2V2 where C1 and V1 are the concentration and volume before dilution. C2 and V2 are the concentration and volume after dilution. Remember this equation. It is extremely useful. Examples: Sam wants to prepare a 250 mL of a solution containing 150 mmol/L of sodium. He has a stock solution of 10%(w/v) sodium chloride.
