What are the respective concentrations (M)of Cu⁺² and Cl^- afforded by dissolving 0.871 mol CuCl₂ in water and diluting to 259 mL? A)3.36 and 6.73 B)0.00336 and 3.36 C)0.00336 and 0.00336 D)3.36 and 3.36 E)0.297 and 0.113

Question

Quizplus · Accepted Answer

The correct answer is A because 0.871 mol CuCl2 in 259 mL of solution gives:[Cu2+]=0.871 mol/0.259 L=3.36 M[Cl−]=2×0.871 mol/0.259 L=6.73 M
