Question

100.0 mL of 1.00 M KOH is added to 150.0 mL of 1.00 M HCl in a calorimeter with a heat capacity of 95.0 J K-1 . When the reaction is completed, the temperature of the solution increases from 25.00 to 29.98 oC. The specific heat and density of the solution are given as 4.2 J g-1 K-1 and 1 g mL-1, respectively.

i) Calculate the standard enthalpy of neutralization between KOH and HCl.
can you show me how to calculate it.
{57.02 kJ/mol}

Answer 1

\(H^o=m*C_p*\Delta T\)

Answer 2

use the density to find the mass, m.
plug in your values and solve.
