## Related Questions MOLARITY = mole of solute / L solution # of moles of solute Molarity = -------------------------- 1 Liter of solution  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 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".  There are several formulae involving molarity, depending on what you are measuring. However the simplest is; If you have x moles of solute in y ml of solution, Molarity = 1000 x/y  Molarity = moles of solute/Liters of solution Molarity = 5 moles solute/4.5 Liters of solution = 1 M solution ========== It depends on how much you are trying to make and what you are diluting it from, but the formula for figuring it out is Molarity of starting solution times X (in which X is how much you will be adding) equals Molarity of the solution you are producing times its volume Molarity of a solution depends upon volume of solution, the change in temperature changes the volume so molarity changes. Molarity of a solution is defined as the number of moles, or for ionic compounds such as NaCl, gram formula masses, of solute contained in exactly 1 liter of solution. The gram formula mass of NaCl is 58.44, and 725 mL is 0.725 liter. The molarity is therefore [(23.1/58.44)/0.725] or 0.545, to the justified number of significant digits. why molarity is preferred over molarity in expressing the concentration of a solution molarity (M) is the concentration of moles (n) of a solute per liters (v) of solution M=n/v 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.  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. == Molality== (1000xMolarity)/((1000xdensity of solution)- (MolarityxMolecular weight of Solute)) == Normality is the number of equivalents (how many H+ ions) times molarity of the substance. The molarity of a substance is the number of moles of a solute per liters of solution. Molarity is defined as grams of solute dissolved in 1 liter of solution and molality is defined as grams of solute dissolvd in 1Kg of solvent  ###### ChemistryBiochemistryElements and CompoundsScienceChemical Engineering Copyright © 2020 Multiply Media, LLC.
