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 17.8 oc before mixing and 32.4 oc after mixing. the heat capacity of the calorimeter is 12.1 j/k. from these data, calculate δh for the process: cuso4(1m)+ 2koh(2m) →cu(oh)2(s) + k2so4(0.5m)
