i bought a KMC SL10X 10 speed chain intended for building a light ss bike, I can't find any single speed freewheel that will fit a 10 speed chain, I also bought a sram s100 ss crankset and it is compatible with 10 speed chain. I am looking for a freewheel that will fit the chain, any suggestions?? I am new to the cycling world and I don't know much about bike components

Wrong Chain, Way wrong, over bought.. You need an 1/8" wide chain, probably ..

a 10 speed cassette has 10 cogs on it , and so you probably got the wrong crankset too too thin, and tooth profile is designed to shift off and onto.
all those Ramps pins and shortened teeth are shifting aides for the index systems.

see if you can exchange it for a Track Crank , or replace the thin aluminum chainring with a thicker one ..
I like Surly stainless steel Chainrings for single speed applications
the tooth profile is better as well as being more durable.

single speed stuff is thicker . 3/32 inch is more a 6,7,8 type chain if you need to adopt a derailleur chain..
but single speed by definition is not space limited , so a wide chain will be fine..

I use 3/32" chains on my Internal gear hub bikes ,
essentially a single speed drive train, externally.

You're probably not going to find one. Almost all freewheels and singlespeed cassette cogs run either a 1/8 or 3/32 sizing (single speed or 9 speed). The added weight between a basic 10speed chain and a basic singlespeed chain is barely anything. It'll be much easier to just get the right chain. Your 10speed compatible chainring shouldn't have a problem holding a 1/8 smoothly.

can i buy a single 10 speed cog and somehow mount it to the hub and ride it as a fixed gear? is it possible? my rearwheel has a flip flop hub

Not in any way that's worth the effort, considering the low price of 3/32 and 1/ 8 chains.
If you insist on using what you've already got I suppose it'd be possible to grind/file a 3/32 sprocket until it fits a 10 speed chain though.

Find a good home for the 10-speed chain and buy the correct one.

Old 10 is way different than new 10. which usually sells as 20 "speed"

A fixed gear chain needs to be stronger than a 10 speed chain bucause the braking force is generally much higher than the accelerating force.
