I think you mistook 5cal for 5kcal

Explanation:

Using the equation DeltaQ=mcDeltaT, we know
m=100
c=4.184

If we assumed that you meant 5 kilocalories, then DeltaQ would be 5*4184=20920 (joules)

20920=100*4.184*DeltaT
DeltaT=50

Therefore if your initial temperature was 20, the final temperature would be 20+50=70ºC.
