1. What are other methods of moisture determination besides oven drying?
2. During the drying of samples, the weight is considered constant when the last two weights are within 0.0003 grams. What is the reason for this?

For #2, could it have something to do with the sensitivity of your balance?

I really don't know, but what I know is that the balance has an uncertainty of 0.0002 g.
