This presents a problem because the amount of NaHCO3 will cause a concentration calculated strictly from the mass of NaOH used to make the solution to be higher than the actual concentration. To account for how much sodium hydroxide is actually dissolved in solution, Mrs. Atkins will titrate the NaOH solution with a primary standard, potassium ...

Confirm that the molarity of the resulting is approximately 3.87 M. (Hint: first find the moles of salt present before the additional 275 mL of water was added by using equation #2 and then find the new molarity using equation #1.) Calculate the molarity of the solution formed by taking 350 mL of 2.25 M HCl and adding 420 mL of water.

Density is usually expressed as g/mL; the density of water being 1.0 g/mL. If we were to calculate the molarity of water (this is a favourite for calculations assignments) the strategy would be as follows: Density of water = 1 g/mL = 1 000 g/L. The molecular weight of water is 18. Therefore the Molarity = 1 000/18 mol/L = 55.5 M.
