## Related Questions   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 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 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. Molarity is a measurement of concentration. It is the number of mols of a solute in the number of L of solvent. Molarity doesn't depend on the chemical properties of the solute, only the concentration. Therefore, the molarity of acetone in water has no specific value, it is merely the # of mols per L of water in whatever sample is being measured for Molarity. 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. 80g of NaOH dissolved in 250ml. of water find the molarity of this solution ? specific gravity is 1gm per cc that means 1000 gm per liter and molarity is gm per liter /molecular weidgt = 1000/18\ we have, gm/lt= Molarity*Mol mass so, 1000=molarity*18(for water H2O) thus, molarity= 1000/18 When you take a solution and make it pure, thus removing the solvent and returning the dissolved compound to its pure molarity       Molarity means number of moles in a solute volume. So molarity is 2moldm-3.   Yes it does, because it will change the number of litres, and molarity is mol/litre. Yes it does, because it will change the number of litres, and molarity is mol/litre. Pure water is pure because it is pure... and because it is pure, it is pure... Got it... What sought of question is that? Depending on the volume of water ! For 1 L, the molarity is approx. 0,1.  since molarity = (number of moles) / (volume of solution), the molarity of a solution with 2.3 moles of sodium chloride in 0.45 liters of water will be 5.11 moles.
