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
Answer:
0.4 ml will be affect the density.
Explanation:
Given that,
A student filled the graduated cylinder up to the 9.6 mL mark.
Recorded volume = 10.0 mL
We know that,
Density :
Density is equal to the mass divided by volume.
In mathematically,
Where, m = mass
V = volume
Affect the density :
Affect the density is equal to the change in volume.
We need to calculate the affect the density
Using formula of affect the density
Put the value into the formula
Hence, 0.4 ml will be affect the density.
