Perfluorocarbons (PFCs), hydrocarbons with all H atoms replaced by F atoms, have very weak cohesive forces. One interesting consequence of this property is that a live mouse can breathe while submerged in O₂ -saturated PFCs.(b) According to one source, kH for O₂ in water at 25°C is 756.7 L?atm/mol. What is the solubility of O₂ in water at 25°C in ppm?

Respuesta :

42.24 ppm is the solubility of O₂ in water at 25°C.

What is Henry Law constant ?

The gas law that states that if the constant is in terms of solubility or pressure.

It is expressed as

[tex]S_{\text{gas}} = k_{H} \times P_{\text{gas}}[/tex]          

where,

[tex]S_{\text{gas}}[/tex] = Solubility of gas

[tex]k_{H}[/tex] = Henry's Law constant

[tex]P_{\text{gas}}[/tex] = Partial Pressure of gas

Now put the values in above equation

[tex]S_{\text{gas}} = k_{H} \times P_{\text{gas}}[/tex]          

       [tex]= \frac{1\ \text{mol}}{756.7\ \text{L.atm}} \times 1\ \text{atm}[/tex]

       = 0.00132 mol/L

Convert the solubility into 1 mg/L

Solubility in ppm = [tex]0.00132\ \frac{\text{mol}}{L} \times \frac{32\ g}{\text{mol}} \times \frac{10^3\ mg}{1\ g}[/tex]

                            = 42.24 ppm

Thus from the above conclusion we can say that 42.24 ppm is the solubility of O₂ in water at 25°C.
