Final answer:
To calculate the mole fraction of substances in a solution, convert the masses to moles, sum the total moles, and divide the moles of each substance by the total moles.
Step-by-step explanation:
To calculate the mole fraction of each solute and solvent, follow these steps:
Divide the moles of each substance by the total moles to get their mole fraction.
Add the moles of H₂SO₄ and H₂O to find the total moles in solution.
