The entropy of vaporization of water is 109.0 j/mol × k at its normal boiling point. what is the enthalpy of vaporization of water at this temperature?

The entropy of a system can be calculated by the ratio of the total heat in the system and the temperature. Entropy is a measure used in thermodynamics to approximate the degree of disorder in a system. From the equation for entropy, we can calculate the enthalpy as follows:

S = H / T
109.0 J / mol K = H / 373.15 K
H = 40673.35 J / mol

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
