An engineering student wants to study the heat transfer between a 50 g of a heated block of iron (cFe = 0.449 J/g ⁰C) at 500 ⁰C and 100 g of water (cH2O = 4.184 J/g ⁰C) at 10 ⁰C using a calorimeter. The same student wanted to determine the heat of dissolution for potassium chlorate (KClO3, MW: 122.55 g/mol) in water. He measured 10 grams of KClO3 and dissolved it in a calorimeter containing 250 g of water. The temperature drop was 3.5 K.
