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!
Density of silver: 10.49g/mL Density of water: 1g/mL Total mass: 1464g Total volume: 700mL x = volume of silver, mL y = volume of water, mL 10.49x + 1y = 1464 x+y = 700 9.49x=764 x=80.5058mL of silver 10.49x = 10.49 × 80.5058 = 844.51g of silverProbably an over estimate [of just the silver] due to the copper so probably more like 835-840g. [If just evaporating, the mass would be higher due to the lower density of the impurities like copper sulfate, so more around 845-850g. E.g. 5mL of copper sulfate would be 830g of silver and 18g copper sulfate = 848g]
Damn, you were faster than I was, I was just calculating the same thing. All I have left is to assume that they won’t be able to fully dry the silver and guess a bit higher… 850g.
Unfortunately for you, I’ve got a hot plate and it gets pretty darn hot.
Also if your melting it into a bar, the furnace would likely dry it enough for most to consider it “dry”
Unfortunately you weren’t the closest (ended up being 817g and some people undercut you) but I will give you the award for most sensible calculation.
