Question
A copper bracelet is placed in a graduated cylinder full of water. The water level rises from 15.6 ml to 28.0ml. The mass of the bracelet is 101.7g. Is the bracelet made of pure copper? How would I know? How would I explain?

volume = mass/density
the volume of this thing =28.0-15.6
= 12.4 mL
so the density = 101.7 g/12.4 mL
= 8.2 g/mL
Is that the density of copper ?
