Solution

The correct option is B $3.58 \times 10^{- 5} M$
The expression for Henry's law is $C = k P_{g a s}$

Substitute values in the above expression:

$C = (0.00105 M / a t m) (0.0341 a t m) = 3.58 \times 10^{- 5} M$

The molar solubility in water (saturated with air) is $3.58 \times 10^{- 5} M$

Hence, the correct answer is option $B$ .

Compute the molar solubility of water that is saturated with air.[Given: k= 0.00105 M/atm, PNe in air = 0.0341 atm]

The correct option is B 3.58×10−5MThe expression for Henry's law is C=kPgasSubstitute values in the above expression:C=(0.00105M/atm)(0.0341atm)=3.58×10−5MThe molar solubility in water (saturated with air) is 3.58×10−5MHence, the correct answer is option B.
