Answer check please
@Vocaloid
yeah that's what i got too
couple of things since nf = 2 and ni = 9 E = 2.183e-18 * (1/2^2-1/9^2)
also this only gives you energy in joules (I think?) per atom, you need to divide by 1000 to get kJ and multiply by avogadro's number
I got -5.180x10^-19
Oh okay so this is in joules so to get it in KJ I would just do the conversion so ?KJ=-5.180x10^-19 * (1KJ/1000J) = -5.18x10^-22KJ
getting there then since this is only one electron, we need to multiply by avogadro's number to get the desired quantity, kJ/mol
oh okay, so on top of this I have to multiply by 6.022x10^23
ANd I have to do this because this is the mol quantity?
yes
-311.9396 KJ/mol
good but only three sig figs so -312 kJ/mol still not 100% sure on the sign convention but try -312 for now
I have the .091 part but is that all of it or do I have to do something more
what
|dw:1537831727187:dw|
since we want wavelength we can just use the original rydberg equation 1/x = (1.096776e7)(1/3^2 - 1/7^2)
998270 m
almost, just need to invert the quantity at the end 1/998270 m
1.00x10^-6 m
good
that looks like a hard expression, what grade is that?
How do I know n=4 from the electron spectrum
r u talking to me?
