Saha ionization equation I plug in the #, i still dont get same answer

[leonne]

Homework Statement

In my notes, they give an example of Saha ionization equation. Its astrophysics.

Homework Equations

N11/N1=(2K(T)(Z11)/pe(z1))(me(k)(t)/(2pi(h)²)^3/2 e^-x1/(kt)

The Attempt at a Solution

They say z1=2, z11=1 pe=15g/cms² x1=13.6ev T=5770k me =electron mass
h=Planck's constant k=Boltzmann's constant
so i plug them in and i get nothing what they got. The answer they have is 7.4e-5. Am i doing something wrong? for the constants i picked the ev units and tried the cgi units and still way off i am guessing final answer has no units cause they didn't have any units by the answer

Hello, it seems like you have the correct equation and values for the constants. However, it's possible that you made a mistake in your calculations or in entering the values into your calculator. I would suggest double checking your work and also making sure you are using the correct units. It's also important to note that the answer you got may be slightly different from the one given in the notes due to rounding or significant figures. I hope this helps!
