The mass of water evaporated is 32.7 g.

What is evaporation?

The term evaporation is the movement of the molecules of water from the surface of the water into the atmosphere. The molecules that move are the more energetic molecules that are able to break away from the attractive field of the surface of the water.

We have the original mass of the water as 455.2 g and the mass of the water after evaporation as 422.55 g. The difference between the two according to the right number of significant figures is 455.2 g - 422.55 g = 32.7 g
