Calculate the density at the centre of the Sun

[artworkmonkey]

Homework Statement

Assuming you know the core mass, and other data about the sun, such as temperatures and pressures. Find the density at the very center of a star.

Homework Equations

I think this may be involved.

P(r) = p(r)/µm_H kT(r)

The Attempt at a Solution

[/B]
I don't know where to begin with this. I tried changing the equation to make density the subject, but when I plug figures in I seem to be way off. I thing I maybe going down the wrong path.

 

[artworkmonkey]

I rearrange the equation to be p(r)=µm_HP(r)/kT(r)
maybe this is not the right equation.

P(r) = p(r)/µm_H kT(r).

Impossible to say without knowing how all those variables defined.
