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),ether (d = 0.708 g/mL).If a rubber stopper (d = 1.2 g/mL)is dropped into the cylinder,where does it come to rest?

Question

Quizplus · Accepted Answer

The rubber stopper will come to rest on top of the chloroform layer because its density (1.2 g/mL) is less than that of chloroform (1.49 g/mL) but greater than that of water (1.00 g/mL), meaning it will sink through the water and ether layers but float on the chloroform layer.
