1 g requires 80 cal of heat, then 100 g requires 80*100=8000 cal

1 cal = 4.1868 J

Then Q = 1910.767 J

for you:

The heat energy is defined from the equation:


Q=mCΔ
T

where

  • Q: the heat energy in (Joules).
  • m: the mass of the material which is heated in (kg).
  • C: the specific heat capacity in (J/kg.K).
  • Δ
    T: the change in the temperature in (K)
