"\\rho = {m \\over V}"

"\\rho = {39.73 g \\over 25.00mL} = 1.5916 g\/mL \\approx 1.59 g\/mL"

Assuming a water density of about 1 g/mL carbon tetrachloride will be located UNDER the water layer, as its density is higher.


Answer: 1.59 g/mL; no, it will not float on water, but will be located under a layer of water.
