Calculate the Amount of Energy Necessary to Raise the Temperature

Calculate the amount of energy necessary to raise the temperature of 1 cup of water at 23°C to steam at 105°C. The specific heat capacity of water is 4.184 J·K^-1·g^-1 and the specific heat capacity of steam is 4.215 J·K^-1·g^-1. The density of water can be assumed to be 1.00 g·ml^-1. For water, DH_vap=40.66 kJ·mol^-1. 1 cup=0.2366 L

A) 81.2 kJ
B) 122 kJ
C) 534 kJ
D) 616 kJ
E) None of the above
