If 55.0 kJ of heat are added to 20.0 g of water at 20oC, what is the final temperature of the system?
Answered by DrBob222
q = mass x specific heat x (Tfinal-Tinitial)
Post your work if you get stuck.

So far i have
deltaH= 20g x 4.18 j/g deg C x 80 deg
= 6.688KJ

AND

DELTA H= 1.11mol x 40.8 KJ/Mol
= 45.3 kj

but i don't know what to do next :(
