The AHcomb value for anethole is -5539.2 kJ/mol. Assume 0.845 g of anethole is combusted in a calorimeter whose heat capacity (Calorimeter) is 6.643 kJ/C at 20.605 C. What is the final temperature of the calorimeter? Number o C Tools x 10 v Check Answer Q View Solution Hint i Dora

Explanation / Answer

Molar mass of C10H12O = 120+12+16 = 148 g/mol

heat of combustion of 148 g. of C10H12O = -5539200 J

then heat of combustion of 0.845 g o anesole = - 5539200 X 0.845 / 148 = 31625.84 J

q = C(t2 - t1)

31625.84 = 6643 ( t2 - 20.605)

t2 = 25.366 degree C
