10.00 mL of a sample of concentrated hydrochloric acid is diluted to 1000.00 mL. If a 20.00 mL portion of this diluted acid required 15.23 mL of 1.5 M NaOH to reach endpoint, what the concentration of the original, Undiluted HCL

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
