If 64.0 kJ of heat is added to a 45.0g sample of liquid ethane, C2H4 under 1 atm of pressure at a temperature of -165.0 C, what is the final state of ethane once the system has reached equilibrium? What is the final temperature once the system equilibrates?

Assume that no heat is lost

The normal boiling point of ethane is -88.5˙C delta vap= 9.45 kJ/mol

The specific heat of liquid and gaseous ethane are 4.78 and 2.45 J/g K, respectively
