You have two simultaneous equations to solve, and they depend upon the resisitivity and the density, which you will have to look up.
1)0.500 ohms = (resistivity)*L/(pi*D^2/4)
2)0.900 g = (density)*L*pi*(D^2/4)
I suggest using centimeter, g/cm^3 and ohm-cm units.
The product of mass and resistance, which you know, will let you solve for L.
