"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.

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.


Moles of a solute per kilogram of a solvent?

The number of moles of solute dissolved in 1 L of a solution would be the molarity. As an example, if you had 2 moles of solute in 1 liter the molarity would be 2M.


How are molarity and molality similar?

Both express moles of solute in the numerator.


Why you use molality in biology experiments?

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.


Is 0.001mhcl a strong acid?

HCl is a strong acid no matter the molarity or molality.


Is molality or molarity expressed in grams of solute instead of moles of solute?

Molarity is a measure of the concentration of a solution, and therefore cannot be said to be just moles.It is in fact moles per litre (mol/L), or molars.


What terms are used to describe solutions with different amounts of solute?

Molarity or Molality


What quantity represents the ration of the number of moles of solute per kilogram of solvent?

Mol is a cocentration unit !


What is the molality of a solution that has 4 mol of KCl in 0.800 kg of water A.?

4 mol over 0.800 kg


Why molality is not temperature dependent?

Molarity is the no of moles of solute per dm3 solution, the temperature change changes the volume so molarity becomes effected.


Molarity is to moles of solute over liters of solution as molality is to?

moles of solute over kg of solvent
