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.

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

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