A drop of liquid toluene is kept at a uniform temperature of 25.9°C and is suspended in air by a fine wire. The initial radius of the droplet was 2.00 mm. The vapor pressure of toluene at 25.9°C is 3.84 kPa and the density of liquid toluene is 866 kg/m3. a. Derive the equation to calculate the time required for the drop to evaporate completely in a large volume of still air. Show all steps. b. Calculate the time (min) for complete evaporation.
