Answer #1

I need more info for this. I actually need the total pressure exerted by the system. In that way we can apply the following expression:

PH2 = XH2 * Pt

We can assume that if you have the volume of the container and the temperature we can actually calculate the total pressure:

Pt = (0.220+0.350+0.430) * 0.0821 * 273 / 22.4 = 1 atm

the total moles are also 1, so XH2 = 0.350 / 1 = 0.350

Which means that the pressure of H2:

pH2 = 0.350 * 1 = 0.350 atm.

That's my doubt, but please confirme to me if the total pressure is that, or you have another value of total pressure.

Hope this helps
