A solution contains 25% water, 25% ethanol, and 50% ethanoic acid by mass. Calculate the mole fraction of each component in the same order.

By adding the above three we get:

• Total moles = 1.389 + 0.543 + 0.833 = 2.765
• Mole fraction of water = 1.389/2.765 = 0.502
• Mole fraction of ethanoic acid = 0.833/2.765 = 0.301
• Mole fraction of ethanol = 0.543/2.765 = 0.196

Benefits of the molar fraction

• The mole fraction is not temperature-dependent.
• Calculating the mole fraction does not require knowledge of the phase's density.
• The mole fraction of an ideal gas mixture is represented by the mixture's partial pressure to total pressure ratio.

Summary:

A solution contains 25% water, 25% ethanol, and 50% ethanoic acid by mass. Calculate the mole fraction of each component in the same order.

A solution contains 25% water, 25% ethanol, and 50% ethanoic acid by mass. The mole fraction of each component in the same order is 0.502, 0.196, 0.301. The mole fraction is the product of the number of molecules of a specific component in a mixture and its total molecular weight. It is a means to convey how concentrated a solution is.
