The distance between the centres of carbon and oxygen atoms in the gas molecule is `1.13 Å`. The centre of mass of the molecule relative to oxygen atom is

Options

A. `0.602Å`
B. `0.527 Å`
C. `1.13Å`
D. `0.565Å`

Answer

B

Explanation

Given Interaomic distance `=1.13Å`
Mass of carbon atom =14
Mass of oxygen atom = 16
Let C.M. of molecule lies at a distance of x from oxygen atom
ie..,e `m_(1)r_(1)=m_(2)r_(2)`
`16X=14(1.13-X)`
`30X=15.82`
`X=0.527 Å`
