It means every thing is made out of Atoms and some things are element componds so elements are the "backbone" of the compounds.
ΔS= nΔHvap/T,
Where, ΔS = Change in entropy, n = moles of water = 39.3/18 = 2.188 moles, ΔHvap = 40.67kJ/mol = 40670 J/mol, T = Temperature (K) = 100+272.15 = 373.15 K
Therefore,
ΔS = (2.188*40670)/373.15 = 237.96 J/K
