A fish swimming in water body when taken out from the water body is covered with a film of water of weight 36g. When it is subjected to cooking at 100°C, then the internal energy for vaporization in kJ mol^-1 is_____________. (nearest integer)

[Assume steam to be an ideal gas. Given  ${\Delta }_{vap}{H}^{\Theta }$ for water at 373K and 1 bar is 41.1 kJ mol^-1; R = 8.31 JK^-1mol^-1]
