We shall use the formula; C = q/m*ΔT to calculate the specific heat capacity, where;
C: is the specific heat capacity
q: is the quantity of energy in joules
m: is the mass in grams
ΔT is the difference between T2 and T1

We shall convert the energy to joules first, q = 59.3 * 1000 = 59300J.
Therfore,
C = 59300/ 150* (398-298) = 3.953 J/g.K
