Problem

In a coffee-cup calorimeter,

50.0\,\text{mL}

2.00\,\text{M}

HCl at

25.0^{\circ}\text{C}

is mixed with

50.0\,\text{mL}

1.50\,\text{M}

NaOH, also at

25.0^{\circ}\text{C}

. The final temperature of the combined solution is

31.2^{\circ}\text{C}

. The density of all solutions is

1.00\,\text{g}\,\text{mL}^{-1}

and the specific heat capacity is

4.18\,\text{J}\,\text{g}^{-1}\,^{\circ}\text{C}^{-1}

. Calculate the molar enthalpy of neutralization (in

\text{kJ}\,\text{mol}^{-1}

of water produced).
