Answer:
4.1/
Explanation
Do the calculation carefully because this calculation has negative term.
I hope you will understand.
3/8 + 7/2 + (-3/5) + 9/8 + (-3/2) + 6/5
31/5+(-3/5)+(-3/2)
41/10

The mole fraction of sulfur trioxide in the equilibrium mixture is 0.353.
Hence option (B) is the correct answer.
The ratio of the number of moles of one component of a solution or other mixture to the total number of moles representing all of the components.
We have to use algebra here,
Because in the equation has a stoichometry of 1, the other have 2,
let = x
You started with 2 moles, so the moles of at equilibrium will be 2 - X
has a stoichiometry of 2 compared to
, so will be 2X
( not minus from anything as you started with no moles of )
And then will also be 2X as it’s stoichiometry is 2, but as you started with 2 moles it will be 2-2X
If you add these in an equation to get total moles it’s
2 - 2X + 2 - X + 2X = 3.4 (total given)
and then gathering together becomes 4-X = 3.4
so,
4 = 3.4 + X
so,
x = 0.6
Therefore,
the moles of = 2 x 0.6 = 1.2
mole fraction = moles of the gas / total moles of gas
mole fraction = 1.2 / 3.4 = 0.353
