Calculate the pressure of gas if the solubility of gas in water at 25^ C is 6.85 10^4 ~mol dm ⁻³ (Henry's law constant is 6.85 10^4 ~mol dm ⁻³ bar ⁻¹ )

Options

  1. A0.853 bar
  2. B1.5 bar
  3. C0.5 bar
  4. D1 bar

Correct answer

A. 0.853 bar

Step-by-step solution

We know S = K _ H P In 1 dm ^3 or 1 lit moles of gas dissolved is 6.85 10^4 p =6.85 10^4 / 6.85 10^4=1.0 bar.
