Okay- I need 5 bits to represent 32 coins.I count as coin 0,coin 1,... coin 31.

No, you can't count coin 0. Or how will you represent no coins?

I thought i could use the null set to point to the first coin,simply as a one to one mapping but then i can't represent no coins. Thanks for the clarification.
