Molarity of water is 55.5 mol/L
1000/18 molecular weight (in daltons) = 55.6M
In dilute solutions... ie closer a solution is to pure water the closer molality and molarity come to equalling each other. This is because the molality uses mass and molarity uses volume, the ratio of these two (mass and volume) is density, and water has the density of 1 therefore the mass and volume are equal to each other. THEREFORE calculating the molarity of water is the same as calculating the molality of water.
Molarity is a concentration unit of solutions, pure benzene is not a solution so this term is meaningless for a pure liquid. In other words: Molarity of a solution is a numerical way of saying exactly how much solute is dissolved in a solvent .Molarity is equal to the moles of solute divided by the liters of solution. Molarity of a solution can be calculated by using the following formula: M= moles of solute/liters of solution
Molarity gives the no. of moles of solute per litre of the solutionFor instance, 1 M HCl means 1 mole of pure HCl in 1 L of water
Dissolve 116,879 g of pure NaCl in 1 L demineralized water at 20 0C.
When you take a solution and make it pure, thus removing the solvent and returning the dissolved compound to its pure molarity
VOLUME OF water
Sugar does not have measurable molarity. Molarity is used to determine the concentration of a solute in a solution. For example, you could measure the molarity of sugar in a sugar-water solution.
