A coffee-cup calorimeter is filled with 50 mL of 1 M NaOH and 50 mL of 1 M HCl, both at room temperature. After the reaction is complete, the final temperature of the solution is 32.5 degree C. Using the specific heat of water, calculate the heat of reaction, q (in Joules), and the Hrxn (in kJ/mol) for the neutralization of aqueous sodium hydroxide.

q = mcdT
q = 100*4.184*(Tfinal-Tinitial). You can fill in what room temperature is and calculate q in joules.
q = ? joules for 0.05 mols (i.e., 0.05L*1M) so scale up from 0.05 mols to 1 mol and convert to kJ/mol
Post your work if you get stuck.
