Answer:
Use the formula below
Explanation:
use the moles ratio for this by writing down the reaction and balancing the equation
It is called nuclear energy.
Answer:
0.745 and 0.245
Explanation:
Mole fraction (χ) is the number of moles of a component divided by the total number of moles in a mixture.
We must calculate the moles of each component.
Let CO₂ be Gas 1 and SO₂ be Gas 2.
1. Calculate the moles of each gas.

2. Calculate the total moles.

3. Calculate the mole fraction of each component
