A calorimeter has a mass of 100 g and a specific heat capacity of 0.42 J g-1 K -1
. Into it
are put 60 cm3
of 0.25 mol dm-3
hydrochloric acid and 50 cm3
of 0.25 mol dm-3
potassium hydroxide solutions at the same temperature. The temperature of the
calorimeter and content rises by 5.0 K. Specific heat capacity of the solution = 4.2 J g1 K
-1
