The molar enthalpy of vaporization of water is 40.79 kJ/mol, and the molar enthalpy of fusion of ice is 6.009 kJ/mol. The molar mass of water is 18.02 g/mol. How much energy is absorbed when 30.3 g of liquid water boils

Answer : The amount of energy absorbed is, 81.2 kJ

Explanation :

The process involved in this problem are :

The expression used will be:

where,

= heat required for the reaction = ?

m = mass of liquid = 30.3 g

= specific heat of liquid water =

= enthalpy change for vaporization =

Now put all the given values in the above expression, we get:

Therefore, the  amount of energy absorbed is, 81.2 kJ
