In the reaction h2so4 + 2 naoh -> na2so4 + 2h2o, an equivalence point occurs when 29.43 ml of 0.1973 m naoh is added to a 32.42 ml portion of h2so4. what is the [h2so4]?

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
