  • Successive dilutions of a solution

    , we can see that the final concentration after k dilutions will be: And in our case (k=3): The molar mass of NaCl is: If after the third dilution we have moles then we have: The solution explains how to calculate the final concentration

  • Molarity of NaCl solution

    That is, the number of moles after the dilution is also 0.6 moles. Ok? How much 0.54M NaCl, "physiologic saline" can be prepared via the dilution of 100mL of 6.0 M NaCl solution?

  • Dilutions

    For 1L of working solution, take 20mL of stock and dilute to 1L 7-11. 6 tubes of 1:2 gives a 1:2^6 dilution, or 1:64. 7g/dL is 7000mg/dL, which dilutes to 109.4 mg/dL 7-12. The initial concentration is 0.2mg/mL.

  • Solutions, Acids, Bases Molarity of a Solution

    Calculate the molarity of a solution if 126 mL of 6.25 M NaOH was diluted to a total volume of 250mL. Number of moles of NaOH = Volume of Solution * Molarity = 0.126*6.25 = 0.7875 Molarity after dilution = 0.7875/0.25 = 3.15M 4.

    187222 Molarity Dilution Concentration 0.50 ml of 0.005 M I2 solution is mixed with 3.50 ml of other aqueous reagents. Upon mixing, what is the concentration of I2?

  • Working with molarity,molality and PH

    Therefore: moles of solute before dilution = moles of solute after dilution Molarity = moles of solute/volume of solution in liters Moles of solute = Molarity*liters of solution = 2.56*10 = 25.6 New molarity = 25.6/250 = 0.1024 M
