A 24.93 g sample of ice is heated from -16 oC to its melting point of 0 oC and then melted completely. Next it is raised to its boiling point of 100 oC and boiled completely. Finally the sample is heated to 113 oC. How much energy was absorbed by the sample? (Answer in kJ pay close attention to units!)
Sice=2.1 J/goC Delta Hf = 6.02 kJ/mol
Ssteam=1.7 J/goC Delta Hv = 2.26 kJ/g
