Answer : The solubility is, 
Explanation : Given,
= Henry's law constant of argon = 
First we have to calculate the pressure of argon.
Pressure of argon = 
Pressure of argon = 0.0093 atm
Now we have to calculate the solubility.
As, the solubility of argon in 1 atm pressure = 
So, the solubility of argon in 0.0093 atm pressure = 
= 
Thus, the solubility is,
