amount of heat required to change.....?

Question

Calculate the amount of heat required to change 50.0 g ice at -20.0 °C to steam at 135 °C. (Heat of fusion = 333 J/g; heat of vaporization = 2260 J/g; specific heat capacities: ice = 2.09 J/g·K, liquid water = 4.18 J/g·K, steam = 1.84 J/g·K)

a.32.4 kJ
b.135 kJ
c.156 kJ
d.78.8 kJ
e.4.18 kJ

Answer 1

c.156 kJ
