Answer : The height of the column in a barometer is, 10.3 m
Explanation :
To calculate the height of the column in a barometer we are using formula as:
where,
P = external pressure =
Conversion used :
h = height of the column in a barometer = ?
= density of water =
Conversion used :
g = constant of gravity =
Now put all the given values in the above formula, we get:
Therefore, the height of the column in a barometer is, 10.3 m
Water is technically a compound because it’s made up of hydrogen and oxygen.

Answer:
5.521 × 10⁻² mol/m².s
Explanation:
Given:
Pressure of the Methane and Helium gas = 101.32 kPa
Temperature of the Methane and Helium gas = 298 K
Partial pressure of Methane, pA₁ = 60.79 kPa
Partial pressure of Methane at point 0.02 m away, pA₂ = 20.26 kPa
Now,
Molar flux is given as:
Here,
= 0.675 × 10⁻⁴ m²/s (for He-CH4 at 101.32 kPa and 298 K)
Z₂ - Z₁ = 0.02 m
R is the ideal gas constant = 8.314 J/mol.K
T is the temperature = 298 K
On substituting the respective values, we get
or
= 5.521 × 10⁻² mol/m².s
