Determining the Structure of Water Molecule from Hydrogen and Oxygen Gases - Prof. David C, Assignments of Physics

Instructions for phys 100 students in spring 2008 regarding homework 1. The homework includes exercises from 'physics: concepts and connections' by hobson. One question asks students to determine the structure of a water molecule based on the mass ratio of hydrogen and oxygen atoms in water. The process of electrolysis and the resulting hydrogen and oxygen gases, and asks students to consider the possible structures of water molecules (ho or h2o) and how to determine the correct one based on the masses of the captured gases.

7 Composition of Water
Water can be decomposed (by a process called electrolysis) into hydrogen gas and oxygen
gas. Conversely, combining only hydrogen and oxygen produces water. These observations
indicate that a water molecule consists of hydrogen and oxygen atoms. The issue is the way
in which the two types of atoms combine to produce water. One possibility would be that
one atom of hydrogen (H) and one atom of oxygen (O) combine to produce the molecule HO.
Alternatively two atoms of hydrogen (H) and one atom of oxygen (O) combine to produce
the molecule H2O. The issue is to determine which of this is possibly correct. Suppose that
are able to decompose water into hydrogen gas and oxygen gas and that you can capture all
of these gases that are produced. Knowing that the mass of an oxygen atom is 16 times that
of an hydrogen atom, describe how you could determine which of the two types of molecules
(HO or H2O) represents water.
