What is the millimolar solubility of oxygen gas, o2, in water at 20 ∘c, if the pressure of oxygen is 1.00 atm?

The mili molar solubility of oxygen gas is 41.57 mmol/L

Explanation:

Milimolar solubility is defined as the number of mili moles present in liter of solution.

To calculate the molar solubility, we use the ideal gas equation:

or,

where,

P = pressure = 1 atm

V = volume

n = Number of moles

R = Gas constant =

T = temperature =

Putting values in above equation, we get:

To convert this into milimoles, we use the conversion factor:

1 mol = 1000 mmol

So,

Hence, the mili molar solubility of oxygen gas is 41.57 mmol/L
