$2257 \frac{k J}{k g}$ must be removed from the steam.

#### Explanation:

The referenced website says "The latent heat of vaporization is the amount of heat required to convert a unit mass of a liquid into vapor without a change in temperature." A table on the page says that the heat of vaporization of water is $2257 \frac{k J}{k g}$.
Reference:
https://www.engineeringtoolbox.com/fluids-evaporation-latent-heat-d_147.html

So converting steam of 100c to water of 100c would require removing 2257 kJ of heat from each kg of the steam.

I hope this helps,
