Consider five solutions that all have the same mass of solute in 100.0 mL of solution. Which has the highest concentration as measured in molarity? A) Na₂SO₄ B) NaF C) KCl D) CaCl₂ E) NaCl

Question

Quizplus · Accepted Answer

Molarity is defined as the number of moles of solute per liter of solution. Since all solutions have the same mass of solute, the solution with the highest molarity will be the one whose solute has the lowest molar mass, allowing for more moles of solute per liter. Among the given options, NaF has the lowest molar mass, thus it will have the highest concentration in terms of molarity.
