A3.52 g sample of ammonium nitrate (nh_4no_3) is added to 80.00 ml of h_2o in a constant-pressure calorimeter of negligible heat capacity. the water is stirred until all ammonium nitrate has dissolved. the temperature of the solution drops from 21.6 to 18.1 degree c (nh_4no_3) (s) + h_2o (l) rightarrow nh_4(aq) + no_3(aq) delta h = ?
assume that the specific heat and density of the resulting solution are equal to those of water, 4.18 jw/g and 100g/ml, respectively and assume that no heat is lost to the calorimeter itself, nor to the surroundings.
a. ls this process endothermic or exothermic (circle the correct answer?
b. calculate the heat of solution(delta h)nh_4no_3 expressed in kilojoules per mole of nh_4no_3? heat of solution (delta h) = kl/mol
