Neither. Molarity is moles per litre. Molality is moles in a kilogram.
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
== Molality== (1000xMolarity)/((1000xdensity of solution)- (MolarityxMolecular weight of Solute)) ==
Both express moles of solute in the numerator.
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.
moles of solute over kg of solvent
"MolaRity" is the correct spelling for mass per amount solution."MolaLity" is the correct spelling for mass per amount solvent.The conversions of molality, b, to and from the molarity , c,for one-solute solutions are:c = ρ.b / [1 + b.M]andb = c / [ρ -c.M]where ρ is the mass density of the solution, b is the molality, and M is the molar mass of the solute.
Molarity (moles solute/L solvent) Molality (moles solute/kg solvent)
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.
The molality is the ratio between the mass of a solute (expressed in moles0 and the mass of the solvent (expressed in kilograms). The term is now anachronic.
Molarity (M) is moles of solute per liters of solution. In contrast, molality (m) is moles of solute per kilograms of solvent.
Mass percent = grams of solute/total grams of solution Mole fraction = mols component/total mols mix. Molarity = mols solute/L solution Molality = mols solute/kg solvent Hope this helps :)
in molarity we dissolved no of moles of solute in 1 dm3 volume of its solution but in molality we dissolved no of moles of solute in 1000 gram or 1 kg of solvent in molarity we don't know the exact amount of solvent quantity but in mplality we know the exact volume of solvent ( water)
This is known as the concentration or more technically the molarity or molality of the solution.
- molarity- molality-percentage composition
The molality of this solution is 1,905; to calculate the molarity you need the density of the solution.
(chemistry) the concentration of a substance in solution, expressed as the number moles of solute per kilogram of solventmolality = moles of solute / kg of solvent
Molarity:1.0 mol (NaOH) /L(solution) = 1.0 M NaOHThe conversions of molality, b, to and from the molarity , c,for one-solute solutions are:c = ρ.b / [1 + b.M]andb = c / [ρ -c.M]where ρ is the mass density of the solution, b is the molality, and M is the molar mass of the solute.
it is expressed in molarity. if a mole of solute is dissolved in 1 liter of solution, the solution is said to be have concentration of 1M (M=molarity)
This is the molarity.
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.)
This is called molality.
Molality is expressed as moles solute/kg solvent. Moles of solute = 2. Kg solvent = 6.Molality = 2 moles/6 kg = 0.33 molal
Probably molality (note: this is not a typo). Molality is the number of moles of solute per kilogram of solvent, and is not widely used except in equations dealing with colligative properties. Remember, molality is moles of solute/kg of solvent. It is always clear if you get this value correct because molality is ALWAYS higher than molarity. (This answer has been updated.)
