Molarity is concentration in moles/L (symbolized by M). Molality is a different way of expressing molarity, but in moles of solute/mass of solvent in mol/kg (symbol m). Normality is molarity x number of equivalents (symbolized by N). Equivalents are the ions that it would dissociate into (H+, OH-, e-, etc.)
Molarity is Moles/Liter, Molality is Moles/kg

because molality is independent of temperature and molarity is dependent on temperature further molality is dilute while molarity is concentrated.
This is known as the concentration or more technically the molarity or molality of the solution.
through molarity,molality, normality. through molarity,molality, normality.
Concentrations in molality (moles of solute per kilograms of solvent) are independent of temperature and pressure whereas concentrations in molarity (moles of solute per total volume of solution in liters) are not.
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.
the amount of of solute dissolved into a solvent determines the concentration of a solution. The greater the amount of solute the stronger the concentration. in other words, the properties of molarity and molality determine the concentration of said solution.
If there is not a constant volume, then different, incorrect data could be given when concerning concentration, molarity, molality, etc.
Neither. Molarity is moles per litre. Molality is moles in a kilogram.
== Molality== (1000xMolarity)/((1000xdensity of solution)- (MolarityxMolecular weight of Solute)) ==
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
Both express moles of solute in the numerator.
The concentration of solution means to express the amount of solute in specific amount of solvent or solution, there are different ways to represent the concentration of a solution as, 1-Molarity.. moles/dm3 2-Molality.. moles /K.g 3-Normality .. gram equivalent/dm3 4-Mole fraction 5-ppm 6-ppb.
In chemistry we might use moles per litre. In physics we'd be more likely to use g per litre or g per centimetre cubed.
quantity of solute dissolved in a given quantity of solvent
Molality is used when temperature varies in an exothermic or endothermic reaction because it is not dependent on temperature or pressure. Molality does not depend on tempratute whereas molarity does.
Molarity is an indication for concentration.
molarity (moles solute/liters solution), parts per million (or parts per billion, or thousand, or trillion for that matter), and molality (moles solute/kg solvent)
HCl is a strong acid no matter the molarity or molality.
Molarity or Molality
Yes, molarity is (number of moles/liters of solution). If you increase the numerator, the molarity number will be greater.
"Normality" refers to the activity of a reagent: gram equivelant dissolve in a liter? "Molarity" refers the numbers of moles of the solute present per litre of the solution. "Molality" refers the numbers of moles of solute present in 1000 grams of the solvent. Thus, for hydrochloric acid (HCl) and sodium hydroxide (NaOH) the normality is equal to the molarity. But for dibasic substances like sulfuric acid (H2SO4) or barium hydroxide Ba(OH)2, the normality is twice the molarity. For a tribasic substance, normality would be three times the molarity and so forth.Molarity measures the number of moles of a substance present in per liter of solution. Normality is basically a measure of concentration that is in the mixture of solution.
