# What is the difference between molarity and molarity solution?

123

Molarity solution is not a term that I have ever heard used. Molarity is always a term used to describe a concentration of solute in a solvent, i.e. of a solution. The closest I've heard to molarity solution is when people ask "what is the solution's molarity".

## Related Questions Molarity is the concentration of a solution in moles per litre. Normality is the concentration of a solution in equivalent masses per litre.   The difference is in the denominators.Molarity (M) - the number of moles of solute divided by the number of liters of solution.Molality(m) - the number of moles of solute divided by the number of kilograms of solvent.  Density is the weight per volume of a solution, while the concentration is the amount of particles/molarity per volume.  Molarity = moles of solute/Liters of solution Molarity = 5 moles solute/4.5 Liters of solution = 1 M solution ========== The molarity is a form of expression for the concentration; the molarity of a solution is the number of moles of solute in the solvent. The number of moles is the ratio between the mass of the solute in the solution and and its molar mass. Molarity of a solution depends upon volume of solution, the change in temperature changes the volume so molarity changes. Molarity is the amount of a compound (in this case the solute) related to a known volume of solution. why molarity is preferred over molarity in expressing the concentration of a solution Molarity= (number of moles of solute)/(volume of solution in dm3)  Molarity is an indication for concentration. If you concentrate a solution, the molarity (moles/liter) will increase. 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. Normality is another way to express the concentration of a solution. It is similar in many ways to molarity. The difference is that molarity is way to provide information about the number of molecules in a liter of solution and normality provides information about the number of reactive units in a liter of solution. Molarity is expressed in terms of moles of a compound per liter of solution. (Remember a mole is molecules) Normality is expressed in equivalents per liter. An equivalent can defined as the number of moles of "reactive units" in a compound. One equivalent can either react with or take the place of one mole of hydrogen ions.  Adding more solvent to a solution decreases the molarity of the solution. This is based on the principle that initial volume times initial molarity must be equivalent to final volume times final molarity.     ###### ChemistryElements and CompoundsThe Difference BetweenScience Copyright © 2020 Multiply Media, LLC.
