Asked by AJ
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 µm) 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 kg·m2/s2)?

For 1 you have it correct except that the problem asks for the answer in micrometers and your answer has the unit of meters.
For 2,
E = hc/wavelength.
Remember to convert wavelength from nm to meters and that will give you the energy for one photon. Multiply that by 2 to give you two photons and set that equal to mc^2 to calculate mass.
