Given that the popping occurs due to the internal pressure from water being converted to steam, the unpopped kernel will weigh more. The popped kernel has lost the weight of (some of) this steam.

This site agrees with the above site, but also gives various other information, including experiments to determine the amount of water in the kernals.
