Answer:
Mole fraction ethanol = 0.175
Explanation:
Mole fraction ethanol = Moles of ethanol / Total moles
Total moles = moles of ethanol + moles of water.
Moles of ethanol → 29.2 g . 1 mol / 46 g = 0.635 moles
Moles of water → 53.6 g . 1 mol / 18 g = 2.98 moles
Total moles → 0.635 mol + 2.98 mol = 3.615 moles
Mole fraction ethanol = 0.635 / 3.615 = 0.175
Remember: Mole fraction has no units
