Calculate the molarity of a solution consisting of 65.5 g of K₂SO₄ in 5.00 L of solution.

Question

Quizplus · Accepted Answer

To find the molarity, first calculate the molar mass of K2SO4, which is approximately 174.26 g/mol. Then, divide the mass of K2SO4 (65.5 g) by its molar mass to find the number of moles: 65.5 g / 174.26 g/mol ≈ 0.3759 mol. Finally, divide the number of moles by the volume of the solution in liters: 0.3759 mol / 5.00 L ≈ 0.0752 M.
