The solubility of N ₂ gas in water at 25^ C and 1 bar is 6.85 10⁻⁴ mol L ⁻¹ . Calculate the solubility of N ₂ gas in water at the same temperature when the partial pressure of N ₂ is 0.70 bar
Options
- A5.138 10⁻⁴ mol L ⁻¹
- B5.480 10⁻⁴ mol L ⁻¹
- C4.795 10⁻⁴ mol L ⁻¹
- D4.875 10⁻⁴ mol L ⁻¹
Correct answer
C. 4.795 10⁻⁴ mol L ⁻¹
Step-by-step solution
According to Henry's law, the solubility of a gas in a liquid is directly proportional to its partial pressure at a constant temperature. S P S₁ P₁ = S₂ P₂ Given S₁ = 6.85 10⁻⁴ mol L ⁻¹ , P₁ = 1 bar , and P₂ = 0.70 bar . S₂ = S₁ P₂ P₁ S₂ = 6.85 10⁻⁴ 0.70 1 S₂ = 4.795 10⁻⁴ mol L ⁻¹ Answer: 4.795 10⁻⁴ mol L ⁻¹
