Ethanol 46 g/mol.
Water 18 g/mol.
Calculate moles of ethanol: 14.6 grams x 1 mol / 46 grams = 0.317 moles.
Calculate moles of water: 53.6 grams x 1 mol / 18 grams = 2.98 moles.
Mole fraction = moles of component / total moles in solution.
= 0.317 / (0.317 + 2.98) = 0.0963.
Sulfuric acid 101 g/mol.
Water 18 g/mol.
