a) A laboratory technician adds 56.1mL of concentrated 12 mol/L hydrochloric acid to water to form 500 mL of dilute solution. The temperature of the solution changes from 20.2C to 22.3C. Calculate the molar enthalpy of dilution of hydrochloric acid. (Please show all the steps)

b) What effect would there be on the calculated value for the molar enthalpy of dilution if the technician accidently used too much water so that the volume was actually more than 500 mL. Explain
