## ajprincess 2 years ago Please help:) In an HCl molecule, we assume Cl to be of very heavy mass and H alone oscillating. If the oscillation of the HCl molecule shows a frequency of 9.1949*10^13 Hz, deduce the force constant. given:Avogadro constant=6*10^26 per Kgmol.

isnt this chemistry?

2. lilfayfay

ur on the physics section xD

3. ajprincess

ya I am on physics sec cos this question comes under shm @lilfayfay

4. ajprincess

@mahmit2012 please help me:)

5. mahmit2012

i dont know chem!

6. ajprincess

this come under physics. simple harmonic motion.

7. lilfayfay

ohh it looked like chem lol xD

8. Shadowys

lol I'm curious. The force constant is that of G?

9. Carl_Pham

$\omega = \sqrt{\frac{k}{\mu}}$ where k is the force constant and mu is the reduced mass. You're essentially told to approximate the reduced mass as the mass of the H atom alone, because it's about 35x lighter than the Cl atom.

Thanx a lot:)
