<u>Answer:</u> The mole fraction of oxygen gas is 0.479
<u>Explanation:</u>
We are given:
Partial pressure of methane = 143 mmHg
Partial pressure of nitrogen gas = 469 mmHg
Partial pressure of oxygen gas = 563 mmHg
Total pressure = (143 + 469 + 563) = 1175 mmHg
To calculate the mole fraction of oxygen gas, we use the equation given by Raoult's law, which is:
where,
= partial pressure of oxygen gas = 563 mmHg
= total pressure = 1175 mmHg
= mole fraction of oxygen gas = ?
Putting values in above equation, we get:
Hence, the mole fraction of oxygen gas is 0.479

Explanation:
Hello!
In this case, when writing chemical reactions from the given names we must make sure we know the proper formula for each reacted and produced species; thus, since solid iron (III) oxide is , hydrogen gas is
, solid iron is Fe and liquid water is just
, we can write:
However, since different amount of atoms of iron, hydrogen and oxygen are present at each side of the equation, we balance it by adding the following coefficients to each molecule:
And now it is balanced with two iron atoms, three oxygen atoms and six hydrogen atoms at both reactants and products.
