We were given this formula in class:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]delta E= chR (\frac{1}{1^2} - \frac{1}{inf})[/tex]

the [tex]1/1^2[/tex] is because it is in ground state. So the formula simplifies to

[tex]chR[/tex]

c = 299792000

h = 6.626E-34

R = 10970000

and [tex]1.60217653*10^{19} Joules / eV[/tex]

I get:

[tex]1.36009026784583 * 10^{-37} eV[/tex]

The teacher did it in class and got 13.6 eV

Same answer, just 38 magnitudes off

What am I doing wrong?

** edit ** I figured it out. It's not 19, its -19 for Joules to eV
