According to Henderson–Hasselbalch Equation,
pH = pKa + log [CH₃COO⁻] / [CH₃COOH]
As,
Ka of Acetic Acid = 1.8 × 10⁻⁵
pKa = -log Ka
pKa = -log 1.8 × 10⁻⁵
pKa = 4.74
So,
pH = 4.74 + log [0.85] / [0.45]
pH = 4.74 + log 1.88
pH = 4.74 + 0.276
pH = 5.01
Answer:
Water has a higher boiling point because the hydrogen bonds that form water molecules are stronger than the Van der Waals interactions among methane molecules, therefor more energy must be provided in order to break the hydrogen bonds and allow the water molecules to escape the liquid state.

Because pressure (P) is directly proportional to n # of moles. So in a limited space (volume), as more gas is placed inside the closed container, the higher the pressure of the gas that the particles exert on each other and the container.
