Question

What is the concentration of dissolved oxygen at 500C under pressure of
one atmosphere if partial pressure of oxygen at 50°C is 0.14 atm.
(Henry's law constant for oxygen = 1.3 x 10-mol dm-Patm-1)​

Answer 1

Explanation:

Given data:

P o2 = 0.14atm

Kh = 1.3×10^-3mol dm^-3 atm^-1

formula:

C = P o2 × Kh

= 1.3×10^-3mol dm^-3 atm^-1 × 0.14atm

= 0.82×10^-4 mol dm-3 .
