Answer: The energy released when 4.81 mol of water freezes is 28.9kJ
Explanation:
Latent heat of fusion is the amount of heat required to convert 1 mole of solid to liquid at atmospheric pressure or energy released when 1 mole of liquid freezes to solid at atmospheric pressure.
[tex]\Delta H_{fusion}[/tex] = enthalpy change for fusion = 6.008 KJ/mole
Energy released when 1 mole of water freezes = 6.008 kJ
Energy released when 4.81 moles of water freezes = [tex]\frac{6.008 kJ}{1}\times 4.81mol=28.9kJ[/tex]
Therefore, the energy released when 4.81 mol of water freezes is 28.9kJ
