Question

Q.   Find the increase in entropy of 3.43 kg of liquid oxygen that starts at its boiling temperature, boils, and warms to 22.0 degree C at constant pressure. The specific heat of oxygen gas at constant pressure is 913 J/(kg. C) , heat of vaporization is 213 kJ/kg , and its boiling point is -183.0 C.

I know the answer is 11400 J/K.

But I need the steps all clearly.
