Answer:
1. [H+] = 1 x 10^-4mol/L
2. [OH-] = 1 x 10^-10mol/L
Explanation:
1. From the question given, the pH is 4.0. We can obtain the value of the value of the hydrogen ion concentration [H+] as follows:
pH = —Log[H+]
4 = —Log[H+]
—4 = Log[H+]
Anti-log of —4
[H+] = 1 x 10^-4mol/L
2. Recall: [H+] x [OH-] = 1 x 10^-14
But [H+] = 1 x 10^-4mol/L
1 x 10^-4 x [OH-] = 1 x 10^-14
Divide both side by 1 x 10^-4mol/L
[OH-] = 1 x 10^-14/1 x 10^-4
[OH-] = 1 x 10^-10mol/L

Pressure of the Mixture = 101.4 kpa
Pressure of the helium phe = 82.5 kpa
Pressure of CO2 pco2 = 0.4 kpa.
Partial pressure of oxygen = Pressure of the Mixutre - (Pressure of the
helium + Pressure of CO2)
Partial pressure of oxygen = 101.4 - 82.5 - 0.4
Partial pressure of oxygen = 18.5 kPa
