The distance between carbon and oxygen atoms in CO is 1.2 10-10 m (= 1.2A0).
 
Given, distance between the atoms (x2) = 1.2 A0
Mass of carbon atom (m1) = 12
Mass of oxygen atom (m2) = 16
Consider, the situation when C-atom is located at origin, it is assumed this way because, center of mass has to be calculated with respect to C-atom.
 
Xcm = 12*0 + 16 * 1.2 / 28 = 19.2/28 = 0.68 A
