Question

For electromagnetic radiation with a wavelength of 576.3 nm:
(a) What is the frequency of the radiation (in s-1)? (b) What is the energy (in J) of one photon of
the radiation? (c) What is the energy (in kJ) of one mole of photons of the radiation
So a I go 5.202x10^14 b)3.447x10^-19. C im not sure how to do. I did my answer in b times avagadros constant divided by 1000j and got 207.6 kj. Am i right? An answer asap would really help

Answer 1

Also are a and b correct

Answer 2

wave equation: freq*wavelengt=speed light
a) freq=3E8/576.3E-9 correct
b) energy = Plancks constant* freq Not the way you did it.
c) onemoleengery=above enegy*avag number
