Molar volume, coefficient of thermal expansion and coefficient of isothermal compressibility for water at 20^oC and 1 bar have the following values:

V_m, cm³/mol = 18.02 a, K¹ = 2.07 10⁴ k_T, bar¹ = 44.7 10⁶

Assume that a and k_T are independent of pressure and calculate the molar volume of water at 200 bar and enthalpy change between 1 bar and 200 bar (at 20^oC).
