When $15\mathrm{.}0$ mL of $3\mathrm{.}00$ M NaOH was mixed in a calorimeter with $13\mathrm{.}90$ mL of $3\mathrm{.}00$ M HCI, both initially at room temperature $(22\mathrm{.}0\backslash$deg C$),$ the temperature increased to $30\mathrm{.}40\backslash$deg C$.$ The resultant salt solution had a mass of $28\mathrm{.}90$ g and a specific heat capacity of $3\mathrm{.}74$K$^-1$g$^-1.$ What is the heat capacity of the calorimeter $($in J$/\backslash$deg C$)?$ Note: The molar enthalpy of neutralization per mole of HCl is $-55\mathrm{.}84$ kJ mol$^-1.$
