The distance between the center of carbon and oxygen atoms in the gas

1.	The distance between the center of carbon and oxygen atoms in the gas molecule is 1.13 A. The center of mass of the molecule relative to oxygen atom is –(a) 0.602 Å (b) 0.527 Å (c) 1.13 Å (d) 0.565 Å
Answer» (b) 0.527 Å Inter atomic distance = 1.13 Å Mass of carbon atom = 14 Mass of oxygen atom = 16 Let C.M. of molecule lies at a distance of X from oxygen atom- i.e. m₁ r₁ = m₂r₂ 16 X = 14(1.13 – X) 30 X = 15.82 X = 0.527 Å

The distance between the center of carbon and oxygen atoms in the gas molecule is 1.13 A. The center of mass of the molecule relative to oxygen atom is –(a) 0.602 Å (b) 0.527 Å (c) 1.13 Å (d) 0.565 Å

Answer»

(b) 0.527 Å

Inter atomic distance = 1.13 Å

Mass of carbon atom = 14

Mass of oxygen atom = 16

Let C.M. of molecule lies at a distance of X from oxygen atom-

i.e. m₁ r₁ = m₂r₂

16 X = 14(1.13 – X)

30 X = 15.82

X = 0.527 Å
