Resistor w/ LED Question

Hey guys, not that good with the whole resistor things but I know you can piggy back them to lower/higher the ohm's and what not...

Basically my question is:
I have 4 sets of different resistors- 470 ohm 1/4 watt, 220 ohm 1/8 watt, 100 ohm 1/4 watt, and 1000 ohm 1/2 watt. All I'm trying to do is wire up 2 white leds to a 12v. The resistor calculator calls for a 180 ohm 1/8 watt for this to work properly. Is there anything I can do with my resistors to make this work instead of driving 15 mins to the nearest electronic store for a $1 purchase?

Also- if the leds use 4.5 watts each and would run off a 9v battery, do they need any resistors if I wire 2 up to the 9v battery?

Thanks guys

First I'm going to assume you mean the LEDs use 4.5 VOLTS (not Watts). All you need to do is wire both LEDs in series to a 9V battery.

Put the 220 ohm and 1k ohm resistor in parallel for 180 ohms.

Hook up a single 470 1/4 to each LED, then attach power and ground to each in parallel.

Yep meant volts my bad.

Thanks guys!
