"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]
and
b = 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.
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 :)
as we define mole to be mass of the solute divided by molecular mass of the solute so all the solutes are taken in the solid form not in the liquid like we take 1L in molarity,so solids are generally independent of temp thats why both molality and mole fraction are independent of temperature
Molarity equals normality when the equivalence factor = 1.
molarity is the number of moles dissolved per volume of a solution in dm cube molarity=mass of solute in gram __________________ 1 * _________________ molecular mass of solute volume of solution in dm cube OR molarity=no.of moles ________________ volume of solution in dm cube
Usually such ratios have a specific name. For example, the ratio of a mass measurement (g) over a volume measurement (mL) is called density. The result is a number with the unit g/mL. Most cases that have different units will have a specific name if they're commonly used. Other examples include molarity, molality, joules, newtons, and ppm.

Molarity is better than molality for many applications because it is more commonly used and easily measured in the laboratory. Additionally, molarity accounts for volume changes with temperature, whereas molality does not. This makes molarity more versatile for a wider range of experimental conditions.
Molality is expressed in grams of solute per kilograms of solvent, while molarity is expressed in grams of solute per liter of solution. Both molality and molarity are concentrations that measure the amount of solute in a given amount of solvent, but they are calculated differently.
Both express moles of solute in the numerator.
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.
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.
This is the definition of molality, which is a concentration measure used in chemistry to express the amount of solute in a solution per kilogram of solvent. It is denoted by a lowercase "m" and is calculated by dividing the moles of solute by the mass of the solvent in kilograms.
HCl is a strong acid no matter the molarity or molality.
Mol is a cocentration unit !
4 mol over 0.800 kg
Molality is to moles of solute over mass of solvent in kilograms.
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.
