For these types of questions, the equation Q = m • c • deltaT is used.
Hear Q is the enthalpy or heat transfer, m = mass, c = specific heat capacity and deltaT = change in temperature
In this case, we also convert 57.73 g to 0.05773 kg since c is written in J/kg•K in conventional unites.
1143 = 0.05773 • c • (169.6-20)
c = 132.3 J/ kg • K

In that case you just need to do a conversion from kg to g since K and C are interchangeable here. 132.3 J/kgK • 1 Kg/ 1000 g = 0.132 J/g•C
