Heat of vaporization is the heat required to vaporize unit mass of a substance at it's boiling point. The heat of vaporization or condensation of water is 2257 J/g.
It means that 1 g of water involves 2257 J energy during condensation or vaporization at its boiling point (100 C)
Given mass of water vapor that is condensing = 11.2 g
Calculating the heat released when 11.2 g of water vapor condenses in to liquid water at 100:
Rounding the final answer 25,278 J to three significant figures we get, 25,300 J
Therefore the correct answer is E. 25,300 J
