In an experiment to determine an ethalpy changecalorimetrically, 125.0 cm3 of 0.25 mol dm-3 CsOH were mixed with50.0cm3 of 0.75 mol dm-3 HF in a coffee cup calorimeter. Theinitial temperatures of both solutions were21.50  °C and the final temperature of themixed solutions was 24.40  °C. Assumeall solution have a density of 1.0g cm-3 and a specific heatcapacity of 4.2 Jg-1  °C-1
