Molarity of Pure Water - Laboratory Notes

WebA simple equation for calculating the osmolarity of a solution is derived from the molarity of the solution such that: Osmolarity = Molarity × n n is the number of particles or ions present in the solution. For instance a solution of NaCl will dissociate into two ions that are Na+ and Cl-. How to measure Osmolarity WebThe density of water is known. (See assumptions.) It is 1.00 g / mL, or 1000 g / L if you prefer. What this means is that our liter of water has a mass of 1000 grams. Grams aren’t moles, of course, but grams and moles are related to one another by the molar mass of a molecule – water in this case.
