If you place 1.0 L of ethanol (C₂H₅OH) in a small laboratory that is 3.0 m long, 2.5 m wide, and 2.5 m high, will all the alcohol evaporate? If some liquid remains, how much will there be? The vapor pressure of ethanol at 25°C is 59 mm Hg, and the density of the liquid at this temperature is 0.785 g/cm³.
