The air at the top of Mount Everest has pressures of 201.0 torr N2, 50.0 torr O2, 2.0 torr Ar, and 0.5 torr CO2. What is the tot
1 answer:
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

The molarity of the solution will be 0.72 m.
The majority of reactions take place in solutions, making it crucial to comprehend how the substance's concentration is expressed in a solution when it is present. The number of chemicals in a solution can be stated in a variety of ways, including.
The symbol for it is M, and it serves as one of the most often used concentration units. Its definition states how many moles of solute there are in a liter of solution.
Given data:
Molarity can be determined by the formula:
where, M is molarity and V is volume.
Put the value of given data in above equation.
57.3 × 0.497 m = M × 39.5 L
M = 0.72 m
Therefore, the molarity of the solution will be 0.72 m
