Air is a mixture of gases that is about 78.0% n2 by volume. when air is at standard pressure and 25.0 ∘c, the n2 component will dissolve in water with a solubility of 4.88×10−4 m. what is the value of henry's law constant for n2 under these conditions? express your answer with the appropriate units. enter the unit m using the compound form mol/l.

The value of Henry's law constant for N₂ under these conditions : kH = 6,256 .10⁻⁴ mol/L.atm

In the transfer from the gas phase to the liquid phase, diffusion process occurs.

The solubility of the gas itself decreases with increasing temperature

The partial pressure of gas itself is influenced by the concentration of the gas and temperature

Henry's Law states that the solubility of a gas is proportional to its partial pressure

Can be formulated

S = gas solubility, mol / L

kH = Henry constant, mol / L.atm

P = gas partial pressure

The gas partial pressure is proportional to the percentage of the gas volume in the mixture

In the standard 25 C state, the air pressure is considered to be 1 atm, so the partial pressure of N₂ -Nitrogen becomes:

P = 0.78 atm

Nitrogen gas solubility itself 4.88 × 10⁻⁴ M (mol/L)

so the constant H:

kH = S / P

kH = 4.88 × 10⁻⁴M / 0.78

kH = 6,256 .10⁻⁴

grams of CO will dissolve in 1.00 l of water

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

: )

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
