I’ll be drying the silver out and weighing it sometime in the next couple days. Closest guess when I do gets bragging rights! (And absolutely nothing else)
The scale was zeroed with the beaker empty, and it contains only water and silver (and a trace amount of copper nitrate). If you have a strategy behind your guess, please do share it!
I’m chemically refining some 90% silver coins I had into pure silver. I first dissolved them in nitric acid, then added copper to selectively precipitate the silver.
