A sulfuric acid solution is labeled 8N (where IN = 1 g-equivalent /L, and I mol of H2SO4 contains two g-equivalents). The specific gravity of the solution is 1.230, and its heat capacity is 3.00 J/ (g∙°C). Calculate the specific enthalpy of this solution (in kJ/mol H2SO4) at 60°C relative to pure H2O and an infinitely dilute solution at 25°C.
Answer to relevant QuestionsUse Table B.11 to determine the specific enthalpy (kJ/mol HCI) of hydrochloric acid containing 1 mol HC1/5 mol H2O at 25°C relative to:(a) HCI (g) and H2O (l) at 25°C.(b) H2O (1) and an infinitely dilute HCI solution at ...Two hundred kilograms per hour of an aqueous solution containing 20.0mole% sodium acetate (NaC2H3O2) enters an evaporative crystallizer at 60°C.
