What is the concentration of an AlCl₃ solution if 150.mL of the solution contains 550.mg of Cl^- ion? A) 3.45 × 10^-2 M B) 8.25 × 10^-2 M C) 1.03 × 10^-¹ M D) 3.10 × 10^-1 M

Question

Quizplus · Accepted Answer

To find the concentration of AlCl3, first calculate the moles of Cl- ions: 550 mg Cl- = 0.550 g Cl- = 0.550 g / 35.453 g/mol = 0.0155 mol Cl-. Since each AlCl3 provides 3 Cl- ions, moles of AlCl3 = 0.0155 mol / 3 = 0.00517 mol. Concentration = 0.00517 mol / 0.150 L = 3.45 × 10^-2 M.
