Calculate amount of heat which needs to be added to 25.0 g of ice,

initially at -15°C, to convert it to steam at 120°C. Following information may be useful:
Specific heat of ice is 2.108 J/g°C
Specific heat of water is 4.184 J/g°C
Specific heat of steam is 1.996 J/g°C
H vap of water = 40.65 kJ/°C
H fus of water = 6.02 kJ/°C
Melting point of water is 0°C
Boiling point of water is 100°C
