The volume of a solution of NaCl at 25ºC is given as:

V/cm³mol^-1 = 1002.9 + 16.40 m + 2.5 m² - 1.2 m³

A: water  B: NaCl

If V_A^*= 18.069 cm³ find the expressions for the partial molar volumes of NaCl and water in this solutions.

ATTEMPT:

m should mean m/m⁰ (molality) and V should mean V_m



Now what? Am I going in the right way? I don't see how I could relate this to V_A^*.
