A50.0 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 degree celsious before mixing and 26.3 degree celsious after mixing . the heat capacity of the calorimeter is 12.1 j/k. from the data, calculate delta hfor the process
cuso4(1 m)+2koh(2 (oh)2(s)+k2so4(0.5 m)
assume that the specific heat and density of the solution after mixing are the same as those of pure water and that the volumes are additive.

= heat absorbed by the calorimeter
= heat absorbed by the solution
= specific heat of calorimeter = 
= specific heat of water = 
= mass of water or solution = 
= change in temperature =
