any one know much about mountain bikes

[Brow tine]

Just a quick question my bike broke on me my back sprocket is just spinning on my back tire. I thought I threw the chain but it's still on I'm guessing I broke what ever attaches the sprocket to the hub. Any pointers on fixing it will be greatly appreciated. Thank u very much.

You blew all the guts in the rear drive, I did this several times, just go to local bike shop and get an new rear wheel complete, cheaper than replacing the hub itself. Cost me like 76 bucks but if you upgrade it can get up to 300

Mulepackhunter is spot on. You can rebuild it but a lot of work and new one is more value.
