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#.
