Answer:
0.02405 g/L is the solubility of argon in water at 25 °C.
Explanation:
Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.
To calculate the molar solubility, we use the equation given by Henry's law, which is:
[tex]C_{Ar}=K_H\times p_{gas}[/tex]
where,
[tex]K_H[/tex] = Henry's constant = [tex]1.40\times 10^{-3}mol/L.atm[/tex]
[tex]p_{Ar}[/tex] = partial pressure of carbonated drink = 0.51atm
Putting values in above equation, we get:
[tex]C_{Ar}=1.40\times 10^{-3}mol/L.atm\times 0.430 atm\\\\C_{Ar}=6.02\times 10^{-4}mol/L[/tex]
Molar mass of argon = 39.95 g/mol
Solubility of the argon gas :
[tex]6.02\times 10^{-4}mol/L\times 39.95 g/mol=0.02405 g/L[/tex]
0.02405 g/L is the solubility of argon in water at 25 °C.
