The density of air at 20°C and 1atm is 1.205g/L. If this air were compressed at the same temperature to equal the pressure at 40.0m below sea level, what would be it's density. Assume the barometric pressure is constant at 1atm. The density of seawater is 1.025g/cm³​

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.

what is the question here. i think you messed up.
