The distance between the carbon atom and the oxygen atom in a carbon monoxide molecule is `1.1 Å`. Given, mass of carbon atom is 12 a.m.u. and mass of oxygen atom is 16 a.m.u., calculate the position of the centre of mass of the carbon monoxide molecule

Options

A. `6.3 Å` from the carbon atom
B. `1 Å` from the oxygen atom
C. `0.63 Å` from the carbon atom
D. `0.12 Å` from the oxygen atom

Answer

C

Explanation

`m_(C) r_(C)= m_(O) r_(O)`
`rArr 12 xx x= 16 xx (1.1 - x)`
`rArr 3x+ 4x= 4.4`
`rArr x= (4.4)/(7)= 0.63 Å`
