What is the boiling point change for a solution containing 0.841 moles of naphtalene (a nonvolatile, nonionizing compound) in 250.0 g of liquid benzene? (Kb = 2.53degrees Celsius/m for benzene).
How many moles of HCl need to be added to 150 mL of 0.50 M NaZ to have a solution with a pH of 6.50? (Ka of HZ is 2.3e-5). Assume negligible volume of the HCl.
