# Pressure problem

 P: 499 I have a somewhat unique question here. I know that $$Pd$$ is a very good absorper of hydrogen. My question is, supposing you start with a given volume of $$Pd$$ and a given volume of $$H$$ or even $$H_2$$ and it is absorped by the $$Pd$$ is it possible to calculate the pressure that the hydrogen is under while it is inside the lattice structure of the $$Pd$$?
 P: 499 I wish to know the pressure that the hydrogen is under when it is absorped by the palladium. A given volume of $$Pd$$ will absorp a given amount of hydrogen. Since the volume of the $$Pd$$ remains constant, there must be a pressure exerted on the hydrogen to keep it within. I wish to know how to calculate that pressure.
