Somewhere in there is the pickle problem:
You have 1000kg of pickles in your basement. Now, pickles are mostly water. In fact, your pickles are 99% water, the rest is cellulose. Cellulose has negligible mass, so we can say that all the mass comes from the water. You leave your pickles in the basement for a year, and when you come back, they've dried out a certain amount, so they're now 98% water. What's their new mass?
