I have the data but I am having a hard time determining the end result.
How much heat energy is required to raise the temp. of 5.0g of H20 from -10C to 110C ? (ice to steam)
Given the following data:
Specific Heat J/gK Molar Heat Capacity J/molK Formula Mass
Water (l) 4.184 75.3 18.0
Ice 2.05 36.9 18.0
Water Vapor 1.84 33.1 18.0
Fusion -- 6.01 kj/mol
Vaporization -- 40.67 kj/mol

Solution Summary
This solution is provided in 181 words. It demonstrates through five steps, including heating, melting, heating again, boiling, and heating the steam, how much total heat energy is required.
Solution Preview
This should be done in 5 steps.
Heat the ice to 0 C by:
q = mc(Tf-Ti)
q1 = 5.0 g(2.05 J/gK)(0-(-10))
q1 = 102.5 J
Melt the ice
q = n(Fusion)
n = m/MM
n = 5 g /18 ...
