Both these things are “brass” but one has a more golden hue and the other more coppery. Latter might even be a bronze. Is there any way to tell?

I guess I could immerse in water and measure volume by displacement, then weigh, and use density to figure out composition 🤔

Assuming that it’s brass / copper through out yes. Brass has a density of 8.73 g/cm^3 copper is 8.96. That’s super close
