10 Bags of Coins

Ten bags are full of coins. All the coins look the same, but those in one of the bags weight 1 gram less than those in the other nine bags. You have a scale like the one shown in the picture, but are permitted to make only one weighing. Any number of bags will fit on either side of the scales.

How do you find out which bag contains the lighter coins?
