Question
If 0.120 moles of water are produced in the reaction
H+(aq)+OH-(aq)-->H2O(l)
delta H=-56.2 kJ/mol
I have tried this problem a ton of times and aris keeps telling me I'm incorrect. Can you please help me with solving this problem

Am I missing something?
First, what's the question? Is it to calculate the heat released by the reaction? Or is it something else?
56.2 kJ/mol x 0.120 mol = 6.744 kJ which rounds to 6.74 kJ to three significant figures (s.f.). I OFTEN find that when students are keying answers into a data base that the problem is incorrect number of s.f.
