What is the mole fraction of H 2 S O 4 in a solution containingthe percentage of sulfuric acid and water shownin Figure 14.25?

Interpretation:
The mole fraction of H2SO4 in the sulfuric acid solution is to be calculated.
Concept introduction:
Mole fraction: Mole fraction defined as the number of moles of one component divided by total the number of moles in the mixture.
The mole fraction for the solute(
Answer to Problem 84A
The mole fraction of
Explanation of Solution
Given information:
The solution contains:
Let assume, the mass of the solution = 100 gm
So, the mass of H2SO4 = 27.3 gm and the mass of water = 72.7 gm
(Note: Molecular weight of sulfuric acid = 98.1 gm/mol)
(Note: Molecular weight of water = 18 gm/mol)
