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.

In the present investigation it was found that such an extrapolation procedure, applied to data at molalities up to 0.1, yields a curved line, concave upward, and of appreciable slope at low concentrations.
Molalities ranged from 0.1 to 1.0 for a water potential range at 25 [degrees] C of 0.462 to 4.64 MPa.
