1. Calculate the enthalpy change, ΔHΔ�, for the process in which 43.6 gg of water is converted from liquid at 19.3 ∘C∘C to vapor at 25.0 ∘C∘C . For water, ΔHvapΔ�vap = 44.0 kJ/molkJ/mol at 25.0 ∘C∘C and Cs�s = 4.18 J/(g⋅∘C) J/(g⋅∘C) for H2O(l)H2O(l). Express your answer to three significant figures and include the appropriate units. 2. How many grams of ice at -7.1 ∘C∘C can be completely converted to liquid at 18.7 ∘C∘C if the available heat for this process is 5.46×103 kJkJ ? For ice, use a specific heat of 2.01 J/(g⋅∘C)J/(g⋅∘C) and ΔHfus=6.01kJ/molΔ�fus=6.01kJ/mol . Express your answer to three significant figures and include the appropriate units.
