How do you calculate the partial pressure of hydrogen gas?
The same way you calculate the partial pressure of any other gas.........
.....i.e. in a gaseous mixture, the partial pressure exerted by a component gas is the same as the pressure it would exert if it ALONE occupied the container. The total pressure is the sum of the individual partial pressures.
I have just restated
The partial pressure exerted by an individual component is thus proportional to
This is all abstract, but you can bring an actual problem to the table.
