Count the gears in the rear, that's what you buy for. If you have 8 gears, it's 8 speed and requires an 8 speed chain, 9 gears would require a 9 speed chain and so on. Don't worry about how many chainrings you have in the front, it's generally 2 or 3 with older bikes, but that doesn't affect what chain to buy. Going to your local bike shop is always a good idea if you have questions.

Be aware that if the chain is old, worn and/or rusty, a new chain will probably skip on your cassette or freewheel. You are very likely to have to change it too.

And that assuming that the wear on the chain and/or cogs are the only problem with the drive system can be a false one. We see bent der hangers, sloppy loose bearings, off index cable adjustments, rust and more all the time. Having a good shop access the bike verbally (which should take only a few minutes and be for free) is a very good foundation to understanding the bike's real condition. Andy.

If you know the year of the bike look it up on Bikepedia that will tell what you should have fitted, even if you don'nt know it's year you will see its colour, & can work it's year out by that way, also Trek have very good web site listing out all their models years specifications. I've still my old 1999 Trek 800 from new, was out on it today's looks it's age but very good frame, it's 5 speed now with friction shifter, but I cannot remember original I think it was 7 speed. Worth keeping cheap in its day but much better frame material than you will find on a modern cheap bike, yes it's heavy.
