## Homework Statement

I have an equation with all known variables and I have the answer...I just can't figure out how they converted the variables and came about the answer.

The first equation is N/V = [2*pi*(2.315)/h^3][2*m*kT]^3/2

we have the known variables h (plank's constant)= 6.6261E-34 j*s or 4.1357E-15 ev*s

m= 6.64E-26 kg

kT= 2.5249E-2 eV

we know 1ev= 1.6022E-19 J and 1 J= kg*m^2/s^2

The answer to this equation is N/V= 2.5E28m^-3

I tried it many times and can't figure out the conversion factors to make this work!

thanks in advance
