Calculate the solubility of certain gas in solvent with pressure 3 atm at 25^ C (Henry's law constant is 3.0 10⁻² , mol dm ⁻³ , atm ⁻¹ )
Options
- A0.07 M
- B0.08 M
- C0.09 M
- D0.1 M
Correct answer
C. 0.09 M
Step-by-step solution
According to Henry's law, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. S = K_H P Given: K_H = 3.0 10⁻² mol dm ⁻³ atm ⁻¹ P = 3 atm Substituting the values: S = (3.0 10⁻² mol dm ⁻³ atm ⁻¹) 3 atm S = 9.0 10⁻² mol dm ⁻³ Since 1 mol dm ⁻³ = 1 M , the solubility is 0.09 M . Answer: 0.09 M
