This question is based on Dalton's Law of Partial Pressure which states that "the total pressure of a system of gas is equal to the sum of the pressure of each individual gas (partial pressure).
Now, Partial Pressure of a gas = (mole fraction) × (total pressure)
⇒ Partial Pressure of Hydrogen =

×
= 0.31 atm
Thus the Partial Pressure of Hydrogen in the container is
0.31 atm.
Because copper has a higher electrical and thermal conductivity than iron and is not susceptible to oxidation as easily.
Answer:

Explanation:
Hello,
In this case, we can compute the required volume by using the ideal gas equation as shown below:

Thus, solving for the volume and considering absolute temperature (in Kelvins), we obtain:

Best regards.
