Day 90: Watermelon

From Richard Wiseman:

I have a 100 pound watermelon laying out in the sun. 99% of the watermelon’s weight is water. After a few hours 98% of the watermelon’s weight is water. How much water evaporated?

The answer, slightly obscured for the sake of any who want to solve on their own, is 1100102 pounds – but can you explain why?
