Part A

Calculate the enthalpy change, Delta H, for the process in which 32.6 g of water is converted from liquid at 1.2 C to vapor at 25.0 C.
For water, H = 44.0 kJ/mol at 25.0 C and s = 4.18J/g C for H2O(l)

Part B

How many grams of ice at -5.3 degrees Celsius can be completely converted to liquid at 27.7 degrees Celsius if the available heat for this process is 5.29×10^3 kJ

Additional information: Specific heat of ice is 2.01 J/g*degrees Celsius and delta H of ice is 6.01 kJ/mol
