Calculate the heat released when 84.6 g of gaseous ethanol at 90.0°C is converted to liquid ethanol at 54.2°C. The boiling point of ethanol is 78.4°C. (See 10.39 for heat constants that may be useful in answering this question.)
Reference Question 10.39:
Calculate the heat absorbed when 125 g of liquid ethanol at 25.0°C is converted to gaseous ethanol at 96.0°C. The boiling point of ethanol is 78.4°C, the specific heat of liquid ethanol is 2.44 J/(g °C), the heat of vaporization of ethanol is 3.86 × 104 J/mol, and the specific heat of gaseous ethanol is 1.42 J/(g °C).
