How much heat is lost when 0.440 mol of steam condenses at 100 °C?

17,890 J

Explanation:

The amount of heat released by a gaseous substance when it condenses is given by the formula

where

n is the number of moles of the substance

is the latent heat of vaporization

The formula can be applied if the substance is at its vaporization temperature.

In this problem, we have:

n = 0.440 mol is the number of moles of steam

is the latent heat of vaporization of water

And the steam is already at 100C, so we can apply the formula:
