I am trying to do density determinations on a large number of individual rock samples. I know the standard dry weight - wet weight methods but have an idea that might be better.
I can buy a completely water proof digital scale. My question is this " can accurate wet weight values be obtained by submerging the scale, zeroing it, and then weighing the rock sample on the submerged scale. The rock would be completely submerged as well.
I cannot fugure out the fatal flaw in this method, but suspect that there is one.
Any help with this question would be greatly appreciated.
