An iron sphere with a mass of 75.00 g is heated to a temperature of 385 0 degree C It is then placed in a beaker containing 150.0 g H_2 O at 100 0 degree C How much heat energy must the water absorb to boil away completely? kJ What is the maximum amount of heat the iron can release to the water? kJ C_p Fe = 0 422 J/g middot degree C Delta H_vap water = 40 7 kJ/mol Delta H_fus water = 6 01 kJ/mol C_p water = 4 18 J/g middot degree C molar mass of water = 18 00 g/mol molar mass of iron = 55 85 g/mol
