500 g of toluene is charged into a glass flask at 22°C and heated in a magnetically stirred electrical heater. The power of electrical heater is 62 W. a. Calculate the time at which toluene reached 60°C. Neglect evaporation of toluene during the heating. b. Calculate the time at which toluene starts boiling? c. Calculate the quantity of evaporated toluene after 40 minutes. d. Calculate the time at which all toluene evaporated to laboratory having a volume of 100 m3. e. Write expression to find toluene concentration in laboratory after all toluene evaporated, find the molar composition of toluene in laboratory. (All windows are closed in the laboratory, temperature of laboratory is 25°C). Data: Heat capacity of toluene is 158.4 J/molK, heat of vaporization of toluene is 37 kJ/mol, boiling point of toluene is 101°C and molecular weight of toluene is 92 g/mol. 500 g of toluene is charged into a glass flask at 22°C and heated in a magnetically stirred electrical heater.
