Question

select the correct answer. waters heat of vaporization is 2,257 joules/gram. how much energy is released when 11.2 grams of water vapor condenses into liquid? a. 202 j b. 2,246 j c. 3,840 j d. 9,950 j e. 25,300 j

Explanation:

Step1: Identify the formula

Energy = Heat of vaporization×mass

Step2: Substitute values

Energy = 2257 J/g×11.2 g

Step3: Calculate result

Energy = 2257×11.2 = 25278.4 J≈25300 J

Answer:

E. 25,300 J
