Question

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.

Answer 1

isnt this chemistry?

Answer 2

ur on the physics section xD

Answer 3

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

Answer 4

@mahmit2012 please help me:)

Answer 5

i dont know chem!

Answer 6

this come under physics. simple harmonic motion.

Answer 7

ohh it looked like chem lol xD

Answer 8

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

Answer 9

\[\omega = \sqrt{\frac{k}{\mu}}\] 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.

Answer 10

Thanx a lot:)
