Question

In carbon monoxide molecule, the carbon and the oxygen atoms are separated by a distance 1.12 × 10⁻¹⁰ m. The distance of the centre of mass, from the carbon atom is(a) 0.64 × 10⁻¹⁰ m(b) 0.56 × 10⁻¹⁰ m(c) 0.51 × 10⁻¹⁰ m(d) 0.48 × 10⁻¹⁰ m

Answer 1

Answer:

A) 0.64 × 10⁻¹⁰ m

Explanation:

Molecule = Carbon monoxide ( Given)

Distance of separation = 1.12 × 10⁻¹⁰ m ( Given)

mass of carbon atom = 12 units

mass of oxygen atom = 16 units

The position of C atom is taken to be the origin

Thus, the position of center of mass -

= 2×16/(12+16)

= 32/18

=0.64 Ao.

Thus, the distance of the centre of mass, from the carbon atom is 0.64 × 10⁻¹⁰ m.
