What are the key concepts in solving 2D Density of States problems?

[Harsha sundar]

Homework Statement

(a) the density of k-states g(k) = L^2*k/2*Pi.
(b) the density of states g(E) = L^2*m/Pi*h^2
(c)The density of states per area n2D(E)=m*/Pi*h^2
(d) Sketch a graph of n2D(E) vs E.
(e) Calculate n2D(E) as a quantity.

The questions don't have to be answered in full a general description and pointing me the right direction itself would be a huge help. Cheers. As this is my first time posting I am not sure of what else to include with the post.
