Answer:
The total air pressure at the top of the highest peak in the world is 253.5 torr
Explanation:
The partial pressures of the gases present at the top of Mount Everest are;
Nitrogen, N₂ = 201.0 torr
Oxygen, O₂ = 50.0 torr
Argon, Ar = 2.0 torr
Carbon dioxide, CO₂ = 0.5 torr
By Dalton's law of partial pressure, the total pressure that a mixture of gases exerts is equal to the sum of the partial pressures of the individual gases
Mathematically, the law can be expressed as follows;
Total pressure, P = ∑P = P₁ + P₂ + · · ·
From which we have;
The total air pressure at the top of the highest peak in the world, Mount Everest, = The sum of the partial pressures of N₂, O₂, Ar, and CO₂
= 201.0 torr + 50.0 torr + 2.0 torr + 0.5 torr = 253.5 torr
= 253.5 torr = 0.33355263 atmosphere
Therefore, the total air pressure at the top of the highest peak in the world, = 253.5 torr
