What is the mole fraction of ethanol in a solution made by dissolving 14.6 g of ethanol,C₂H₅OH,in 53.6 g of water? A)0)0964 B)0)106 C)0)214 D)0)272

Question

Quizplus · Accepted Answer

The mole fraction of ethanol is calculated by dividing the moles of ethanol by the total moles of the solution. The moles of ethanol are calculated by dividing the mass of ethanol by its molar mass (46.07 g/mol). The moles of water are calculated by dividing the mass of water by its molar mass (18.02 g/mol). The total moles of the solution are the sum of the moles of ethanol and the moles of water. The mole fraction of ethanol is then calculated as follows:Mole fraction of ethanol = moles of ethanol / total moles of solution= 14.6 g / 46.07 g/mol / (14.6 g / 46.07 g/mol + 53.6 g / 18.02 g/mol)= 0.0964
