#1. Find the odd one out......!

There are 10 boxes, each containing 10 coins.

In 9 of these boxes, the weight of each coin is 2gms and in the other box the weight of each coin is 1gm.

Given that you can weigh any of the boxes for one single time (a weighing machine is used, not a balance),  how can you find which box is the odd one out (The box with the coin weight of 1gm each)????
