Question

In carbon monoxide molecules the carbon and the oxygen atom are separated by distance 1.2 and strong the distance of the centre of mass from the carbon atoms

Answer 1

mass of the C atom = 12 units

mass of the O atom = 16 units

position of the C atom is taken to be origin.

hence,

position of centre of mass : = 1.2* 16 /(12+16)

= 12*16/28 = 0.69 Angstrom

Answer 2

Answer:

The distance of the center of mass from the carbon atoms 0.685 A°.

Explanation:

Let the distance of center of mass from carbon atom be x and distance of center of mass be (1.2 -x) from oxygen.

Since, there are 2 masses, the center of mass will lie in center or in the middle of the both masses.

Distance of center of mass from carbon atom is equal to distance of center of mass from oxygen.

Mass of carbon = 12 amu

Mass of oxygen = 16 amu

$12amu  \times x=16 amu\times (1.2\AA-x)$

x = 0.685 A°
