Homework Help: Chemistry

Posted by Jake on Sunday, November 30, 2008 at 1:20pm.

Given:
H3PO4(aq) + 3 NaOH(aq) 3 H2O(l) + Na3PO4(aq)
H = -166.5 kJ

What is the value for q (heat) if 4.00 g of NaOH reacts with an excess of H3PO4?

Please can you explain to me HOW to do this, not just give me an answer?
Thanks!
