Assuming the files don't already have any extension at all, then run this from the directory containing the files :-
for file in * ; do mv "$file" "$file".mp3; done
If you want to be extra safe, do this instead :-
for file in * ; do cp "$file" "$file".mp3; done
This will make copies of the files and add .mp3, instead of renaming them. You can always delete the originals afterwards.
Or if you want a graphical interface for mass renaming of files, then have a look at PyRenamer in the Software Centre.

1@piyushmandovra Yes, that's what the first part of my answer does -
for file in * ; do mv "$file" "$file".mp3; donewill rename every file to file.mp3.– Carl HCommented Mar 31, 2015 at 10:59

Use the command rename. It allows perl regexpes. E.g.,
rename 's/(.*)/$1.mp3/' *
Will add ".mp3" to the end of any file or directory name in the directory.
