## molality

[mo-lal´ĭ-te]
the number of moles of a solute per kilogram of solvent. See also molarity.

## mo·lal·i·ty (m),

(mō-lal'i-tē),
Moles of solute per kilogram of solvent; the molarity is equal to mρ/(ltmM), where m is the molality, ρ is the density of the solution, and M is the molar mass of the solute. Compare: molarity.

## molality

/mo·lal·i·ty/ (mo-lal´it-e) the number of moles of a solute per kilogram of pure solvent. Cf. molarity.

## molality

## molality

A fraction of a solution expressed in moles of solute/kg of solvent.

## mo·lal·i·ty

(mō-lal'i-tē)
Moles of solute per kilogram of solvent; the molarity is equal to mρ/(1 + mM), where m is the molality, ρ is the density of the solution, and M is the molar mass of the solute.

Hence, the electromotive-force data of Giintelberg [6] at 20[degrees] and of Roberts, Carmody, Rained and Ehiers, and Anderson and Young at 25[degrees] C for molalities u p to 0,1 m were smoothed to round molalities, where necessary, on a plot of E[degrees]'' as a function of m and are compared in table 8.
