Mole Fraction (X) relates the moles of solute and solvent within a solution:
Assume the total mass is 100 g, so each would have to weigh 50 g.
molar mass ethanol
C2H5OH 2 C x 12.01 g/mol N = 24.02 g/mol
6 H x 1.01 g/mol H = 6.06 g/mol
1 O x 16.00 g/mol O = 16.00 g/mol
Total: 46.08 g/mol
At 63.5˚C the vapor pressure of H2O is 175 torr, and that of ethanol (C2H5OH) is 400 torr. A solution is made by mixing equal masses of H2O and C2H5OH. What is the mole fraction of ethanol in the solution?
