Consider the reaction HCl + NaOH ->NaCl + H2O

HCl Solution: 22 degrees celsius
NaOH Solution: 22 degrees celsius
Final Temperature: 26.1 degrees celsius

A. Calculate the amount of heat evolved when 15 mL of 1.0 M HCl was mixed with 35 mL of 1.0 M NaOH
B. Calculate Delta H per mole of water formed from his data

    15 mL + 35 mL = 50 mL = 50 g assuming volumes are additive and density of the solution is the same as water (1.00 g/mL).
    q = mass H2O x specific heat H2O x (Tfinal-Tintial).
    That is q/50 g. Convert to moles for J/mol or to kJ/mol.
