10 Sacks of pounds Riddle

 We have 10 sacks of golden pounds. Each sack contains at least 10 pounds but we do not know the exact number. One of the sacks contains only phony pounds, while all other sacks contains only real genuine pounds. We know that every phony pound weighs 9 grams and 10 grams each genuine.

 With only one weighing can you find which sack contains the phony pounds?
