It takes 74 mL of a 0.54 M NaOH solution to neutralize 325 mL of an HCl solution. What is the concentration of the HCl solution

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.

answer: i dont know the answer but this might

explanation:

l

yes the answer is total mass in unchanged   : )
