Since the question is incomplete, the table has been searched in order to comply with the question.
Based on the table that I have provided, the order of increasing depth from shallowest to deepest are the following; A,B,C,D,E. The reason that this is the order to be chosen because the one responsible for making water dense is the salt that is on the water and by that, the base is likely to sink whereas the ones with less salt won’t be as thick compared those who have much salt and will skim on its top.

Answer:
we will use the Clausius-Clapeyron equation to estimate the vapour pressures of the boiling ethanol at sea level pressure of 760mmHg:
ln (P2/P1) = -
)
where
P1 and P2 are the vapour pressures at temperatures T1 and T2
Δ vapH = the enthalpy of vaporization of the ETHANOL
R = the Universal Gas Constant
In this problem,
P 1 = 100 mmHg
; T 1 = 34.7 °C = 307.07 K
P 2 = 760mmHg
T 2 =T⁻²=?
Δ vap H = 38.6 kJ/mol
R = 0.008314 kJ⋅K -1 mol -1
ln ( 760/10)=(0.00325 - T⁻²) (38.6kJ⋅mol-1 /0.008314 )
0.0004368=(0.00325 - T⁻²)
T⁻²=0.002813
T² = 355.47K
