1a. When a solid dissolves in water, heat may be evolved orabsorbed. The heat of dissolution(dissolving) can be determined using a coffee cupcalorimeter.
In the laboratory a general chemistry student finds that when1.33 g of CaBr₂(s) aredissolved in 103.70 g of water, the temperature ofthe solution increases from 24.23to 25.85 Â°C.
Based on the student's observation, calculate the enthalpy ofdissolution of CaBr₂(s) inkJ/mol.
Assume the specific heat of the solution is equal to the specificheat of water.
Î”H_dissolution =Â Â kJ/mol
1b. In the laboratory a general chemistry student finds thatwhen 21.18 g ofCs₂SO₄(s) are dissolved in112.90 g of water, the temperature of the solutiondrops from 24.64 to21.92 Â°C.
Based on the student's observation, calculate the enthalpy ofdissolution of Cs₂SO₄(s) inkJ/mol.
Assume the specific heat of the solution is equal to the specificheat of water.
Î”H_dissolution =Â Â kJ/mol
This is all the information the question gives me.
