Answer:
0.91 atm is the partial pressure of just hydrogen gas.
Explanation:
Vapor pressure of water , p= 0.0313 atm
Partial pressure of hydrogen gas = 
Total pressure of the water vapors and hydrogen gas = P = 715 Torr
1 atm = 715 Torr
According Dalton's law of partial pressure:
0.91 atm is the partial pressure of just hydrogen gas.
Added together = 159.7 grams for one mole of Fe2O3<span>. That is moles of hematite, but the question is about iron. We can see there are </span>two<span> iron atoms for every hematite molecule. So the number (moles) of iron atoms is twice the moles of the hematite molecules.
so depending on how much you initially have will determine the answer</span>
P1/V1=P2/V2
1/22.4=4/x
X=4 multiple by 22.4
V2=89.6L
At constant temperature, if the pressure is compressed to the given value, the volume of the nitrogen gas increases to 23.2L.
<h3>What is Boyle's law?</h3>
Boyle's law simply states that "the volume of any given quantity of gas is inversely proportional to its pressure as long as temperature remains constant.
Boyle's law is expressed as;
P₁V₁ = P₂V₂
Where P₁ is Initial Pressure, V₁ is Initial volume, P₂ is Final Pressure and V₂ is Final volume.
Given that;
- Initial volume of the gas V₁ = 22.5L
- Initial pressure of the gas P₁ = 0.98atm
- Final pressure of the gas P₂ = 0.95atm
- Final volume of the gas V₂ = ?
P₁V₁ = P₂V₂
V₂ = P₁V₁ / P₂
V₂ = (0.98atm × 22.5L) / 0.95atm
V₂ = 22.05Latm / 0.95atm
V₂ = 23.2L
Therefore, at constant temperature, if the pressure is compressed to the given value, the volume of the nitrogen gas increases to 23.2L.
