Copper Drift Velocity

A copper wire of resistivity 1.8×108Ωm1.8 \times 10^{-8} \:\Omega\cdot\text{m} and length L=1 mL = 1 \text{ m} is connected to either terminal of a 1.5 V1.5 \text{ V} battery. If the density of conduction electrons is 3×1029 m33 \times 10^{29} \text{ m}^{-3}, find the drift velocity of the conduction electrons in millimeters per second.
