For water, ebulioscopic constant is ke = 0.52 k dmmol 1 and cryoscopic constant kc = 1.86 k dm' moll, respectively. the 0.710 g sample of na2so4 (mr =142.0) was dissolved in water, so that 250 cm of the aqueous solution was prepared. disregarding the osmotic coefficient, calculate a)-c): a) boiling temperature of the prepared solution at normal pressure. a) 100.03°c; b) freezing temperature of the solution. b)-0.112 °c c) osmotic pressure of the solution (p) at 0°c and 25°c.; p=136 kpa (0°c) and 149 kpa (25°c); d) aqueous solution of kcl with concentration 0.5 mol dm freezes at -1.66°c. calculate the osmotic coefficient (o) of this solution. d) = 0.892
