Explanation:
It is known that relation between partial pressure, mole fraction and pressure is as follows.
Partial pressure of gas = mole fraction of gas × Pressure of gas
Therefore, putting the given values into the above formula as follows.
Partial pressure of gas = mole fraction of gas × Pressure of gas
=
= 0.237 atm
According to Henry's law,
Concentration of oxygen = Henry's law constant × partial pressure of oxygen
=
= M
Therefore, calculate moles of oxygen in 5.00 L present as follows.
Moles of oxygen in 5.00 L = volume × concentration
=
= mol
Now, we will calculate the mass of oxygen as follows.
Mass of oxygen = moles × molar mass of oxygen
= mol
= 0.0494 g
or, = 49.4 mg (As 1 g = 1000 mg)
thus, we can conclude that the mass of given oxygen (in mg) is 49.4 mg.
