b)

Mercury will float because the density of mercury is 0.05427 g/mL, which is less than the 1.0 g/mL den

c)

Mercury will sink because the density of mercury is 5.427 g/mL, which is greater than the 1.0 g/mL density of water.

d)

Mercury will sink because the density of mercury is 5,427 g/mL, which is greater than the 1.0 g/mL density of water.
