I have a Cisco 2502 Router with 2 Serial Ports, 1 Aux, and 1 Token Ring interface. Is there a adpater to turn the serials ports into Ethernet?

No dice, my friend. Such device does not exist.

what, may I ask, exactly, are you trying to do? There are 3rd party devices that connect serial devices to an Ethernet connection (turn serial events into SNMP events and send via TCP/IP....)

I'm studying for my CCNA. I would like to add it to my existing network.

You have two choices:  Bridging and Routing.  You can set up a server as a router and buy a token ring card and a MAU to get them talking.  Once the routing or bridge is in place you can see it on the network (fewer problems with routing).  As far as I can tell, that's the cheapest way to use the TKR.  Otherwise, use the HDLC connection on the serial port to connect it to another router in your network with an available serial port.

For CCNA two routers connected via a DTE/DCE cable is what you want.  The DCE side is set up with a clock rate to provide signalling for your serial link.  You should be able to pick up a 25xx series router with a serial port for less than $100US.   The DTE/DCE cable should be readily available for <$30US.

If you look at it - a router IS a serial to Ethernet adapter. Just a big one with interal electronics and an operating system of its own.
You can't connect this router to your LAN unless you do as AutoSponge suggests and put a TR card in a server and turn it into an Ethernet--TR bridge, connect it to a MAU and connect the TR interface to the MAU  
Or, if you have another router with serial and Ethernet interfaces you can put the two back-to-back as netspec01 suggests...

Since there's no TR in CCNA, investing in hooking up that interface is kind of a waste.

This router is really not well suited to CCNA needs.  You could hook one of its serial interfaces to one on another 25xx/26xx series router for some WAN exercises, but these would be more beneficial if you had a way to hook a client to the 2502.  Perhaps you can trade it to someone who needs two serial or TR, for something with both a serial and Ethernet.
