Answer to Question #155277 in Organic Chemistry for Erin

Question

10 kg of water is boiled into steam. What will be the mass of steam created

Answer 1

A water molecule is a water molecule, irrespective if it is densly packed with other water molecules (forming a liquid phase) or if it is widely separated from other water molecules (forming a vapor phase). So it seems obvious that boiling one kilogram of water gives you exactly one kilogram of steam
