Ammonium sulfate, (NH4)2SO4, is often used as a garden fertilizer. If you dissolved 100.0 g of it in water and made 1.0 L of solution:
a. What would the molar concentration of this solution be?
b. What ions would be formed in solution?
c. What is the molar concentration of each ion in solution?

we need the questions , i may then you.

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.
