Phereseadula has to determine the specific heat capacity of milk. He uses a constant volume calorimeter with a heat capacity of 758 J/K and the combustion of acetylene (C2H2) to do the experiment: 2C2H2(g) + 502(g) 4CO2(g) + 2H20(g) ---- ArH = -2610kJ The calorimeter is filled with 1.190L of milk (instead of water). The density of milk is 1.034 g/ cm3. When 4.413 g of acetylene is burned in excess oxygen in the reaction vessel (bomb) of the calorimeter, the temperature of the milk and the bomb increased from 22.5°C to 61.9°C. The heat absorbed by the bomb is:

Question
Transcribed Image Text:Phereseadula has to determine the specific heat
capacity of milk. He uses a constant volume
calorimeter with a heat capacity of 758 J/K and the
combustion of acetylene (C2H2) to do the
experiment:
2C2H2(g) + 502(g)
4CO2(g) +
2H20(g) --- ArH = -2610kJ
The calorimeter is filled with 1.190L of milk (instead of
water). The density of milk is 1.034 g/ cm3. When
4.413 g of acetylene is burned in excess oxygen in the
reaction vessel (bomb) of the calorimeter, the
temperature of the milk and the bomb increased from
22.5°C to 61.9°C. The heat absorbed by the bomb is:
