Calculate the enthalpy change, Delta H, for the process in which 44.0 g of water is converted from liquid at 0.5 °C to vapor at 25.0 °C. For water, Delta Hvap = 44.0 kJ/mol at 25.0 °C and C; = 4.18 J/(g."
• °C) for H2O(1)

Express your answer to three significant figures and include the appropriate units.

How many grams of ice at -15.5 degrees C can be completely converted to liquid at 16.4 degrees C if the available heat for this process is 5.26 x 10 ^ 3 kJ?

For ice, use specific heat of 2.01 j/(g x degrees C) and delta Hfus = 6.01kJ/mol
