A tank has a total pressure of 285 kPa and contains Hydrogen, Oxygen, Carbon dioxide, and Neon. If Neon has a partial pressure of 14 kPa, carbon dioxide is 13 kPa, and Oxygen has a partial pressure of 157 kPa, what is the partial pressure of Hydrogen?

Answer:

Lets the total pressure is Pt and the individual gases are designated as pH2, pCO2, pNe, pO2.

Pt = pCO2+ pNe+pO2+ pH2

285KPa = 13 KPa+ 14 KPa + 157 KPa +pH2

Now add the partial pressure of CO2, Ne and O2 which is equal to 184 KPa.

285 KPa = 184 KPa + pH2

Now subtract the individual pressure of each gas from thje total pressure.

285 KPa - 184 KPa = pH2

101 KPa = pH2

The partial pressure of hydrogen is 101 KPa.
