Answer to Question #249591 in General Chemistry for mas

Question

In the laboratory you dissolve 20.9 g of copper(II) iodide in a volumetric flask and add water to a total volume of 500 mL.

What is the molarity of the solution?  ________M.

What is the concentration of the copper(II) cation?  ________M.

What is the concentration of the iodide anion?  ________M.

Answer 1

Molar mass of CuI = 190.45 g/mol

20.9/190.45= 0.11mol

0.11/0.5= 0.22mol/L
