The Center of Mass of Sulfur Dioxide Sulfur dioxide consists of two oxygen atoms

Question

The Center of Mass of Sulfur Dioxide Sulfur dioxide consists of two oxygen atoms (each of mass 16 u, where u is defined in Problem 40) and a single sulfur atom (of mass 32 u). The center-to-center distance between the sulfur atom and either of the oxygen atoms is 0.143 nm, and the angle formed by the three atoms is 120 degrees , as shown in the figure: http://session.masteringphysics.com/problemAsset/1123762/3/Walker4e.ch09.Pr052.jpg Find x the y and coordinates of the center of mass of this molecule.

Explanation / Answer

1 nanometer (nm) is 10^(-9) meters. As for the center of mass you can use the atomic mass unit U because you only want the result for the POSITION of the center of mass so it makes no difference which mass unit you use
