700 refers to the wheel size (diameter), 25 is the tire width. Tubes will generally have a size and a range of widths they will work with. You want something that says 700 and includes "25" in the range of widths.
This Continental tube has a width range of 25-32: https://www.amazon.com/Continental-Presta-Valve-Black-25-32cc/dp/B008ZTM95C/
EDIT: Amazon isn't too good about linking to specific options. Make sure you select "700 x 25-32mm - 42mm presta valve". The 42mm is the length of the valve. Valve length isn't usually too important, but measure yours to make sure your replacement tube won't be too short or anything. Too long is ok.

As others have stated, always buy a tube that fits your wheel (700 in this case) and your tire width (28mm). Most tubes have a range of widths they will fit so look for any presta valve tube sized 700 x (a range within which your tire width of X-milimeters falls). Again, in your case, X=28. The tube linked above will fit any 700-sized wheel and any tire approximately 25-32mm wide. So it should work fine for you.
Watch some GCN videos on YouTube about how to install the new tube if you've never done it. They'll show you how to avoid pinch flats, which are one of the most frustrating things that can happen when changing a flat.
