There's really no telling, it depends on what size your sprocket and driver/freewheel is, and the length of your chainstays.

Chains are always bought a little too long, and then cut to size using a chain breaker tool.

That would depend on the bike, the size of your chainwheels and the size of your rear sprockets, there's no fixed answer. Your best bet is to mosey along to www.bicycletutor.com, www.parktool.com or www.sheldonbrown.com, they will have detailed instructions on how to determine chain length for each individual setup.

No definite answer, will depend on frame stretch and sprocket sizes. Set the wheel in its most forward position, loop the chain around chainwheel and sprocket, cut chain with least amount of slack. connect chain, move wheel backwards until chain is tight enough. Hand crank wheel, check for tight spots, then do the wheel nuts up properly.

There's really no telling, it depends on the size/design of the frame, and the tooth counts on the sprocket and driver.

Every chain is sold a little longer than needed so that it can be cut to fit according to the bike it goes on to. This means that there's no way of telling how many links you'd need w/o knowing exactly what bike you have.

How many links are in a mongoose model 270 bmx bikes chain?

Good bikes are made in different frame sizes. And dedicated riders often chainge the gearing ratio by replacing either the sprocket or the driver with one with another tooth count than it came with. These things influence chain length, so you see that no one can tell how many links your chain should be. Chains are just about Always bought a Little long, then cut to length on the bike. Faster than counting links. Chain breakers aren't expensive. Either have a shop fit the chain when you buy it, or get a chain breaker (and a quicklink) and fit it yourself. Do note that chain, driver and sprocket wear together, but usually the chain wears the fastest. So sticking a new chain on old sprockets can often lead to the chain skipping and slipping. If you don't know how to measure a chain for wear, better replace aat least chain and driver at the same time.
