Given:
Q = 1728 J
m = 47.6 g
ΔT = 14.8 oC
use:
Q = m*C*ΔT
1728 = 47.6*C*14.8
C = 2.453 J/g.oC
Molar mass of C2H6O,
MM = 2*MM(C) + 6*MM(H) + 1*MM(O)
= 2*12.01 + 6*1.008 + 1*16.0
= 46.068 g/mol
use:
molar heat capacity = specific heat capacity * molar mass
molar heat capacity = 2.453 J/g.oC * 46.068 g/mol
molar heat capacity = 113 J/mol.oC
Answer: 113 J/mol.oC
