As accurately as possible find the residual molar volume of saturated liquid water at 83 bar.

v = 2.512 E-5 m³/mol

Explanation:

∴ P = 80 bar → V = 0.001384 m³/Kg ... sat. liq water table

∴ P = 85 bar → V = 0.0014013 m³/Kg

⇒ P = 83 bar → V = ?

specific volume (V):

⇒ V = 0.001384 + ((83 - 80) / (85 - 80)) * (0.0014013 - 0.001384)

⇒ V = 0.00139438 m³/Kg

molar volume (v):

∴ Mw water = 18.01528 g/mol

⇒ v = 0.00139438 m³/Kg * (Kg/1000g) * (18.01528 g/mol)

⇒ v = 2.512 E-5 m³/mol
