A neutralization reaction releases

5.20\,\text{kJ}

of heat inside a coffee-cup calorimeter containing

100.0\,\text{g}

of aqueous solution

(c = 4.18\,\text{J}\,\text{g}^{-1}\,^\circ\!\text{C}^{-1})

. If the temperature of the solution rises by

11.2\,^\circ\!\text{C}

, what is the calorimeter constant

C_{\text{cal}}

? (a)

463\,\text{J}\,^{\circ}\!\text{C}^{-1}

(b)

46\,\text{J}\,^{\circ}\!\text{C}^{-1}

(c)

4.6\,\text{J}\,^{\circ}\!\text{C}^{-1}

(d)

418\,\text{J}\,^{\circ}\!\text{C}^{-1}
