Given :
Concentration of hydrogen ions, 
.
To Find :
The pH of a solution.
Solution :
We know, pH of a solution is given by :
![pH = - log [ H^+]\\\\pH = -log ( 10^{-3})\\\\pH = 3](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B%20H%5E%2B%5D%5C%5C%5C%5CpH%20%3D%20-log%20%28%2010%5E%7B-3%7D%29%5C%5C%5C%5CpH%20%3D%203)
Therefore, the pH of the solution is 3 .

Answer:
Partial pressure of CO2 = 16 atm
Explanation:
Total number of moles of gases = 4+1 = 5 moles
Mole fraction of CO2 = 4/5
Partial pressure of CO2 = mole fraction of CO2 × total pressure
Partial pressure of CO2 = (4/5) × 20
Partial pressure of CO2 = 16 atm
