21+ Calculate The Mass Of The Reaction Mixture In The Calorimeter
E The mass of the reaction mixture inside the calorimeter is 1521 g. At the instant of mixing you have 1000 mL of a mixture of HCl and NaOH at 220 C.
The specific heat capacity of water is 4184 J g 1 C 1.
. Here 50⁰C is our reaction temperature. I Calculate the magnitude of the heat energy in joules that is released during the reaction. Q m C p ΔT q 7255 g 4184 J g 1.
