## Homework Statement

Estimate the Bose-Einstein condensation temperature of Rb 87 atoms with density of 10^11 atoms per cm^3.

## Homework Equations

[itex]T=\frac{n^{2/3}h^{2}}{3mK_{B}}[/itex]

## The Attempt at a Solution

This should be just a standard plug and chug question, but my answers are not even close to reasonable! I would expect to get anywhere from 500nK to 50nK for an answer, but I am getting thousands of Kelvin! Are my units wrong? I am using Boltzman constant with units of [itex]eV\bullet K^{-1}[/itex] and Plank's with units of [itex]eV\bullet s[/itex].

Then I am using the density in Atoms per m^3 and the mass of a single Rb 87 atom in Kg.

Am I missing something here with units? That is the only thing I can think is wrong.
