- 2.92 A graduated cylinder contains three liquids A, B, and C, which have different densities and do not mix: mercury (D = 13.6 g/mL), vegetable oil (D 0.92 g/mL), and water (D == 1.00 g/mL). Identify the liquids A, B, and C in the cylinder. (2.7) 50 40 30 -B 20 10 2.93 The gray cube has a density of 4.5 g/em2.
