**Tue Jan 29, 2019 2:05 pm**How much heat is required to convert a block of ice of mass 42.30 g at -5.042 C into water vapor at 150.35 C?

So I go through all the calculations (42.3*2.03*5.042+42.3*336.611+42.3*4.184*100+42.3*2259.23+42.3*2.01*50.35) and I end up with the answer 128 KJ but the solution is 132 KJ. Am I missing any steps?
