Carbon dioxide (CO2) 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 CO2 is 0.469 g/cm3 . What is the mass of a 25.0-mL sample of supercritical CO2 at this pressure?

mass = volume x density
You know density and volume, solve for mass.
