A glass cylinder contains four liquid layers: mercury (d = 13.6 g/mL),chloroform (d = 1.49 g/mL),water (d = 1.00 g/mL),and ether (d = 0.708 g/mL).If a marble (d=2.7 g/mL).is dropped into the cylinder,where does it come to rest?

Question

The marble will sink through the ether, water, and chloroform layers because its density (2.7 g/mL) is greater than theirs, but it will float on the mercury layer because its density is less than that of mercury (13.6 g/mL).
