Question

Please help with my Chemistry problem:

The general equation for the energy related to an electron moving from one energy level to another in a hydrogen atom (Eqn 2 in the Introduction information provided in the lab manual) is:

or rearranged,

Then compare your calculated experimental value to the value provided in the equation and discuss any differences in the magnitudes of the values (for the purposes of this report, you do not need to discuss the different signs with these values).

My experimentally determined Rydberg constant was 1.0981455 x 10^7 m^-1

Explanation / Answer

Answer – We are given the experimental value for the constant RH in the equation is

2.18 x 10-18 J.

The experimentally determined Rydberg constant was 1.0981455 x 107 m-1

We need to the convert the determined Rydberg constant m-1 to J

We know formula

E = h*C/

And we also know, 1/ = RH = 1.0981455 x 107 m-1

So, E = 6.626*10-34 J.s * 3.0*108 m/s * 1.0981455 x 107 m-1

           = 2.183*10-18 J

So the given value and the experimental value for the Rydberg constant are same and it is 2.18*10-18 J.
