Will these work in a 2011 21.5 iMac? null

This memory fits most Mac systems. But BEFORE you buy it, click on your apple icon on the top left of your Mac. Click on about this Mac. Then click on memory tab. There it should tell you if your system uses the 1066 MHz speed or the 1333 MHz speeds. Hope this helps.
