According to Henry's law, the solubility of a gas in a liquid is given by the relation:

$S = K_{H} P$

Given $K_{H} = 0.15 mol dm^{- 3} atm^{- 1}$ and $P = 0.15 atm$ .

Substituting the values:

$S = 0.15 \times 0.15$

$S = 0.0225 mol dm^{- 3}$

Since $1 mol dm^{- 3} = 1 M$ , the concentration of the dissolved gas is $0.0225 M$ .

Answer: 0.0225 M
