Homework Help: Chemistry

Posted by AJ on Tuesday, November 4, 2008 at 12:12am.

I need help with these two problems:

1.The H-Cl bond has a frequency of vibration of 8.662 multiplied by 10^13 Hz. What wavelength (in m) corresponds to that frequency?

-is the answer just (3.00x10^8 m*s)/(8.662x10^13 s^-1)

2.A flame has a characteristic color due to emissions of photons of wavelength 525 nm. What is the mass equivalence of 2 mol photons of this wavelength (1 J = 1 kgm2/s2)?
