sample of tetrachloroethylene, a liquid used in dry cleaning that is being phased out because of its potential to cause cancer, has a mass of 40.55 gg and a volume of 25.0 mLmL at 25 ∘C∘C. What is its density at this temperature? Express your answer with the appropriate units. nothingnothing SubmitRequest Answer Part B Will tetrachloroethylene float on water? (Materials that are less dense than water will float.) Will tetrachloroethylene float on water? (Materials that are less dense than water will float.) tetrachloroethylene float on water tetrachloroethylene will sink on water SubmitRequest Answer Part C Carbon dioxide (CO2CO2) is a gas at room temperature and pressure. However, carbon dioxide can be put under pressure to become a "supercritical fluid" that is a much safer dry-cleaning agent than tetrachloroethylene. At a certain pressure, the density of supercritical CO2CO2 is 0.469 g/cm3g/cm3. What is the mass of a 25.0-mLmL sample of supercritical CO2CO2 at this pressure? Express your answer with the appropriate units.
