Final answer:

When 50 grams of water vapor condenses, a total of 112,500 joules of energy is released into the environment as thermal energy, calculated by multiplying the latent heat of condensation (2,250 J/g) by the mass of water (50 g).

Step-by-step explanation:

The question asks how much energy is released by 50.0 grams of condensing water vapor. From the provided information, we know that the latent heat of condensation for water is 2,250 J per gram. To find the total energy released, we multiply this value by the mass of the water condensing.

Energy released = latent heat of condensation x mass = 2,250 J/g x 50.0 g

The calculation gives us an energy release of 112,500 joules. This is the thermal energy released into the environment when 50 grams of water vapor condense.

Answer:

The heat of vaporization of water is 2257-J/g - each grams must release 2257-J of thermal energy. When water condenses its temperature remains constant.

Q = m x Hv ===> 50-g x 2257-J/g = 112,850-J = 112.9-kJ
