The molar concentration of oxygen gas is $8.84\times 10^{-4}mol/L$

Explanation:

To calculate the molar solubility, we use the equation given by Henry's law, which is:

$C_{O_2}=K_H\times p_{O_2}$

where,

K_H = Henry's constant = $1.3\times 10^{-3}mol/L.atm$

$C_{O_2}$ = molar solubility of oxygen gas = ?

$p_{O_2}$ = partial pressure of oxygen gas = 0.68 atm

Putting values in above equation, we get:

$C_{O_2}=1.3\times 10^{-3}mol/L.atm\times 0.68atm\\\\C_{O_2}=8.84\times 10^{-4}mol/L$

Hence, the molar concentration of oxygen gas is $8.84\times 10^{-4}mol/L$
