Data Given:
Molarity = 0.085 M
Ka = 4.5 × 10⁻⁴
To Find:
pH = ?
Solution:
First find out the concentration of [H⁺] Ions using following formula,
[H⁺] =
Puting values,
[H⁺] =
[H⁺] =
[H⁺] = <span>0.00618465843
</span>Or,
[H⁺] = 6.18 × 10⁻³
Calculate pH as,
pH = -log [H⁺]
pH = -log (6.18 × 10⁻³)
pH = 2.20

Explanation:
Hello,
In this case, given the temperature, volume and total pressure, we can compute the total moles by using the ideal gas equation:
Next, using the molar fraction of argon, we compute the moles of argon:
And the moles of methane:
Now, by using the molar masses of both argon and methane, we can compute the mass percent of argon:
Regards.
