Question
The reaction of hydrochloric acid and sodium hydroxide is a very rapid and exothermic reaction.
The equation is: HCl(aq) + NaOH(aq)→NaCl(aq) + H2O(l)

In one experiment, a student placed 50.0 mL of 1.125 M HCl at 25.5º C (density = 1.02 g/mL) in acoffee cup calorimeter. To this, the student added 50.0 mL of 1.225 M NaOH also at 25.5º C (density = 1.04 g/mL). The mixture was stirred, and the temperature quickly increased to a maximum of 32.2º C.

a. Determine the limiting reactant.
b. Calculate the mass of the solution once the HCl (aq) and NaOH (aq) are mixed.
