The Henry's law constant for oxygen is 1 3 10⁻³ ~mol dm ⁻³ ~atm ⁻¹ . If partial pressure of oxygen is 0.46 atmosphere what is the concentration of dissolved oxygen at 25^ C and 1 atm pressure?
Options
- A5.98 10⁻⁴ ~mol dm ⁻³
- B3.53 10⁻⁴ ~mol dm ⁻³
- C5.98 ~mol dm ⁻³
- D2 82 10⁻³ ~mol dm ⁻³
Correct answer
A. 5.98 10⁻⁴ ~mol dm ⁻³
Step-by-step solution
K _ H = S P S = K _ H P S =1.3 10⁻³ ~mol dm ⁻³ ~atm ⁻¹ 0.46 ~atm =5.98 10⁻⁴ ~mol dm ³
