Any resources to help with moles/molarity/concentration etc?

I'm finding Chemistry not as hard some people make it out to be at A-Level, but the whole moles/molarity/concentration thing has me in a bit of a rut.

Anybody know of any online resources that could help me out?

Cheers.

Here are some videos involving solution calculations, the guy also has plenty of other kinds of vids too :wink:
