The reaction can be represented as follows

 
18g H2O (l)  18 g H2O(g)

Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.
Assuming steam behaves as an ideal gas

Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.  =  40.66 kJ mol -1 – (1) ( 8.314 J K-1mol-1)( 373 K) ( 10-3 kJ J-1)
Syntax error from line 1 column 55 to line 1 column 75. Unexpected '<mo '. =  40.66 kJ mol -1 – 3.10 kJ mol -1
         =  37.56 kJ mol -1
