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.)

What is relation between molarity and molality and normality?
"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.
Why molarity is more accurate than molality?
because molality is independent of temperature and molarity is dependent on temperature further molality is dilute while molarity is concentrated.
When is molarity and normality equal with each other?
Molarity equals normality when the equivalence factor = 1.
Are normality and molarity equal in any State?
The normality and molarity are not equal in any state because molarity provides information on the number of molecules while normality provides information on the number of reactive units.
What is the molarity of a 0.050 N H2SO4 solution?
H2SO4 releases two hydrogen ions into solution. Therefore its Normality is twice its Molarity. Or to answer the question, the molarity is half the normality.
Is molality or molarity expressed in grams of solute instead of moles of solute?
Neither. Molarity is moles per litre. Molality is moles in a kilogram.
What is the relationship between Molarity and Normal solution?
normality = number or moles * molarity
What is the difference between molarity and normality?
Molarity is the concentration of a solution in moles per litre. Normality is the concentration of a solution in equivalent masses per litre.

Why molality is preferred over molarity in expressing the concentration of a solution?
why molarity is preferred over molarity in expressing the concentration of a solution
What is the formula between molarity and molality?
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
What is the solution concentration expressed in terms of molarity?
Molarity is Moles/Liter, Molality is Moles/kg
What is formula of normality?
nomality =molarity*valancy factor
What is the normality formula?
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.
What is the formula relation between molality and molarity?
== Molality== (1000xMolarity)/((1000xdensity of solution)- (MolarityxMolecular weight of Solute)) ==
What is the normality of a 1.25 M solution of H2SO4?
Normality - molarity/functionality so 1.25/2 = 0.625N
What is the lab normality of hno3?
One equivalent proton per mole, so molarity is equal to normality.
When does molarity and molality become equal?
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.
Is normality and molarity for silver nitrate same?
