Question

The carbon monoxide molecule (CO) consists of a carbon atom and an oxygen atom separated by a distance of
1.13×10−10m
The mass
mc
of the carbon atom is 0.750 times the mass
mO
of the oxygen atom , or
mC=0.750mO
Determine the location of the center of mass of this molecule relative to the carbon atom.

Answer 1

Answer:

6.46*10^-11m

Explanation:

We can use the equation of the center of the mass of two atoms

$Xcm=\frac{mcxc+moxo}{mc+mo}$

If we take the origin at the center of the molecule carbon monoxice, xc will be 0, so

$Xcm=\frac{moxo}{mc+mo}$=$\frac{xo}{mc/mo+1}$

$Xcm=\frac{1.13.10^-3}{0.750mo/mo+1}$=6.46*10^-11m
