What is the concentration of an AlCl₃ solution if 150. mL of the solution contains 450. mg of Cl^- ion?

Question

Quizplus · Accepted Answer

To find the concentration of AlCl3, first convert 450 mg of Cl- to moles: 450 mg = 0.450 g. The molar mass of Cl is 35.45 g/mol, so moles of Cl- = 0.450 g / 35.45 g/mol = 0.0127 mol. Since each AlCl3 provides 3 Cl- ions, moles of AlCl3 = 0.0127 mol / 3 = 0.00423 mol. The volume of the solution is 150 mL = 0.150 L. Therefore, the concentration of AlCl3 = 0.00423 mol / 0.150 L = 2.82 × 10^-2 mol L^-1.
