Question

If 124.4 mL of water is shaken with oxygen gas at 0.81atm, it will dissolve 0.0036 g O2. Estimate the Henry's law constant for the oxygen gas in water in units of g mL ^-1atm^-1.

Expert Solution

Step 1

Given : Mass of O₂ dissolved = 0.0036 g

Volume of water used = 124.4 mL

And pressure of oxygen gas = 0.81 atm

Since volume of solution = volume of water approx. (because volume of oxygen gas will be negligible)

Hence the concentration of O₂ dissolved is given by,

$= > C o n c e n t r a t i o n o f O_{2} g a s d i s s o l v e d, S = \frac{M a s s o f O_{2} d i s s o l v e d}{V o l u m e o f s o l u t i o n} = \frac{0.0036}{124.4} = 2.894 X 10^{- 5} g / m L$
