In a solution the mole ratio of solute to solvent is 2 to 3. What is the mole fraction of solute?

Answer and explanation

Correct answer: 0.40

Mole fraction is defined as the moles of the chosen component divided by the total moles of all components. The ratio permits us to take 2 mol solute and 3 mol solvent, giving 5 mol total. Thus, solute mole fraction = 2/(2 + 3) = 2/5 = 0.40. Option C is correct; 0.60 is the solvent fraction, while the smaller values do not use the total correctly.
