“Any half competent freshman chemistry student could measure density and tell the difference between gold and tungsten.”
You think? I believe that is false...

You're most like correct, babygene. Density = mass / volume. Here are typical density values.
Gold = 19.32 g/mL
Tungsten = 19.35 g/mL
So a gold-coated tungsten bar would have a density a bit below 19.35. Perhaps it would be 19.34.
A chemist just might catch that if he had a VERY precise massing device and a VERY precise volume device. Typical high school lab devices would not catch that small a difference.
And to make it even more confusing, not all scientists will agree on those given densities! There are fluctuations due to temperature, etc. Bottom line, forget density as a test here.
I do think. That’s why I said it.
