What you have to keep in mind is that 
pH   =  - log[H+]
so 3.75 = -log[H+], we get [H+]=10^{-3.75},
that is [H+]≈1.77827941×10^{-4}(i see this result on calculator)
this is just what you want!

An unknown liquid has a vapor pressure of 88 mmhg at 45°c and 39 mmhg at 25°c. What is its heat of vaporization?
Elis [28]

The relation between vapour pressure , enthalpy of vapourisation and temperature is

ln(\frac{P1}{P2} ) = \frac{deltaH}{R} (\frac{1}{T2} - \frac{1}{T1})

ln (88/ 39) = DeltaH / 8.314 (1 / 318 - 1 / 298)

0.814 = DeltaH / 8.314 (2.11 X 10^-4 )

DeltaH = -32.07 kJ
