The back wheel on my bike has popped/punctured. I need to know a way to fix it without buying a new wheel. If there is no way then I might as well buy a new wheel. Also, I need to know a good way of finding the hole in the wheel, because I can't seem to find it. Oh and my wheel size is 24" in case you need that info.

Most likely, all you need is a new tube. Look on the side of your tire to find its size and width; it will be raised print that says something like 24 x 1.75. Get the corresponding tube at your local bike shop.
To change it, you will need some tire levers (available at any bike shop) to remove the tire. Insert the tire lever under the bead of the tire on one side and use it to pop part of the tire off the rim. Work the tire lever around until the entire side of the tire is out of the rim. You should be able to then pull the other side of the tire free - if it is difficult, use the tire lever again to get it started.
Pull the punctured tube out and either patch it (patch kits are also available at any bike shop) to keep as a spare or toss it in the garbage. To find the puncture, put some air in it and see where it leaks. If you can't find it, submerge it in water and see where the bubbles come out.
Before you put the new tube in the tire, check the inside of the tire carefully to make sure that no glass or other foreign objects are still lodged in it. If there is a hole in the tire itself, you will either need to boot it (boot kits are available at any bike shop) or replace the tire.
Assuming the tire is fine, put a little bit of air in the new tube and place it in the tire. Seat one side of the tire in the rim and put the valve stem through the hole. Then begin seating the other side of the tire starting opposite the valve stem and working your way toward it. The last portion can be difficult to seat and you may have to use your tire levers again to get it on completely. Check to see that the tube is not trapped under the bead of the tire by squeezing the tire back so that you can see the inner part of the rim (iif you can see the inside of the rim without any tube sticking under it, you are good). This simple check ensures that you won't pinch flat. Then pump up your tire and away you go.
If all of this seems like too much, go to a bike shop and have them change the flat for you. It should only cost about $15. Watch the mechanic as he or she changes it and you will know how to do it for yourself next time!

Other than buying a new tube, there is the distinct possibility that you will have to repair a puncture while out riding, especially if you ride a road bike. While I carry a spare tube, a second puncture would definately require a patch, so...
Tools:
2 - Tire Levers
1 - Pump (or C02 cartridges/adapter)
1 - Patch Kit.
Procedure:
1. Try to locate the cause of the puncture and remove from tire if found
2.As the tire is flat, insert one of the tire levers in between the tire and the rim. Insert the second tire lever a few inches further along the rim. Push down on the first lever to "lift" one side of the tire off the rim, repeat with the second lever.
3.Once you have a section of the tire off the rim, push the second lever around the rim, until the tire is sitting half on the rim, and half off the rim. This may require alternating levers, without having the tire "snap" back on the rim.
4. Pull the inner tube out from between the tire and the rim, leaving the stem connected to the rim.
5. Pump up the tire, and you should begin to hear it "hiss", showing where the hole is. If you do not hear it, the best method is to dip the tube in a bucket of water and look for bubbles. if no water is available, carefully run your hand around the tube and feel for air, or hold it close to your cheek and feel for air.
6. Once the hole is found, dry it off and remove any "powder", and roughen the area with the sand paper in the patch kit. The sand paper will increase the adhesion of the glue.
7. Some patch kits contain "pre-glued" patches, if so just peel and stick. If not, apply enough glue to cover the hole, and the surrounding area that the patch will cover, wait the amount of time stated on the glue (usually seconds), and apply the patch, smoothing the edges and ensuring good adhesion.
8. Put tube back into tire around rim
9. Reverse procedure for tire, and re-seat on rim.
NOTE: Be careful not to pinch the tube against the rim/tire.
10. Give the tire a few pumps of air...."massage" where tire meets rim, to ensure that it is seated, and the tube is not pinched.
11. Full inflate tire.....happy trails.
Pull out

Take your inner tube. Pump air into it and then dunk into a bucket of water (A little soap is good.) This will tell you where the hole is. Patch with a puncture repair kit (Dry off, put glue over area, when tacky put on patch.) Run hands over inside of wheel and find any sharp objects (Be carefull with this.). Pull out any thorns etc. Now partially inflate tube and place inside tyre. Re-fit tyre and then re-inflate. Check that tyre is fitted properly after putting about 10psi in, before fully inflating.
If the hole is too big, or you have several holes, you might have to buy a new inner tube.
Luck

i suppose this is the tube. take off the back tire by quick release or by loosing the nuts. remove the chain from the sproket without tangeling it. deflate the tube as much as u possibly can. use tire levers to pry the tire off the rim and pull the tube out. replace the tube or patch it if you can. replace by filling the tube a little bit and placing it inside the tire. mount the tire on the rim and replace the wheel on the frame keeping the chain on the same gear it was before. to check where the whole is inflate your tire and use your upper lip to feel for the air comming out. you can usually hear it if you fill it up enough to find a closer spot then randomly checking.
