The wattage or the current value must also be given. Else you can't find resistance with just one given value.

Assuming that you're asking about a common incandescent lamp, the resistance will be 2.2 ohms, but only once the bulb has reached its final operating temperature. However, its initial resistance, immediately upon introduction of the voltage, will be about one-twelfth that value.
