Homework Answers
Mass of water is 0.850 kg. Convert unit from kg to g.
The molar mass of water is 18 g/mol
calculate number of moles of water
(1) 47.22 moles of gaseous water are cooled from 121 deg C to 100 deg C (the boiling point)
Calculate the heat released
(2) 47.22 moles of gaseous water are condensed at 100 deg C (the boiling point).
Calculate the heat released
(3) 47.22 moles of liquid water are cooled from 100 deg C to 32 deg C (the boiling point)
Calculate the heat released
(4) calculate heat released in entire process
Convert unit from J to kJ
