What is the specific enthalpy of superheated steam

Question

Solve the following problem:

The specific heat capacity at constant pressure of steam at atmospheric pressure is given by

C_P = a + bT + cT²
 
where a = 1.912 kJ/kg.deg
         b = 1.727*10^-3 kJ/kg.deg²
         c = -4.667*10^-6 kJ/kg.deg³

If the specific enthalpy of saturated steam at 100°C is 2676 kl/kg, what is the specific enthalpy of superheated steam at the same pressure and a temperature of 300°C?
