A 50.0 mL sample of a 1.00 M solution of CuSO4 is mixed with 50.0 mL of 2.00 M K

Question

A 50.0 mL sample of a 1.00 M solution of CuSO4 is mixed with 50.0 mL of 2.00 M KOH in a calorimeter. The temperature of both solutions was 20.2 degrees Celsius before mixing and 26.3 degrees Celcius after mixing. The heat capacity of the calorimeter is 12.1 J/K. From this data calculate the ?H for the process. Assume the specific heat and density of the solution after mixing are the same as those of pure water. Report your answer with two significant figures.

CuSO4(1M) + 2KOH(2M) to form Cu(OH)2(s) + K2So4(0.5 M)

Explanation / Answer

elevation of temperature is 26.3-6.1=6.2
