If you have the newer 21.5" iMac EMC 2805 (Mid 2014) model.

I'm sorry to tell you this model has soldered LPDDR3 memory (8 GB) which is not upgradable.

If you take a look at this image of the logic board you will see the 4 black chips in a row between the persons hands: Logic board (top side)

Update

Just to be clear here you have a Late 2013 model not the newer Mid 2014 model.

As adlerpe stated you can replace the RAM modules, but its a big job!

You'll need to take the entire system apart to get to the RAM slots. Here's the IFIXIT guide you'll need to follow: iMac Intel 21.5" EMC 2638 RAM Replacement. Be very careful taking the display off as it can be easily damaged if you don't use the correct tools and don't take your time. Many people have killed theirs which would make the RAM upgrade quite expensive!

Boy are these conflicting answers! What did you think of the upgrade links I gave?

If he had the older version of the newer 'Thin Series' models with removable RAM, you need to completely take the logic bd out to get to them. Unlike the 27" which has an access door. This newer model doesn't offer one a choice. It is what it is ;-{

pablo, go to "About This Mac" (under the Apple in the menubar), click on the System Report button, and tell us what the Model Identifier name is. iMac14,1 or iMac14,3 are the Late 2013 generation, which has two PC3-12800 SODIMM slots, where you can install 16GB RAM. iMac14,4 is the Mid 2014 generation, which has soldered/non-upgradeable RAM. Or you can post the last four numbers of your serial number, and we can look up the model of your system using EveryMac.com. Either way, we should make sure that the model in the upper right corner of this page is the computer we're actually talking about.
