A chemist must prepare 800. mL of 69.0 µM aqueous mercury(II) iodide (HgI,) working solution. He'll do this by pouring out some 0.000101 M aqueous mercury(II) iodide stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the mercury(II) iodide stock solution that the chemist should pour out. Round your answer to 3 significant digits.

Expert Solution
Step 1

Given : Volume of solution to be prepared = 800 mL

Concentration of HgI2 = 69.0 µM = 69.0 X 10-6 M                                         (since 1 M = 106 µM )

And concentration of HgI2 stock solution = 0.000101 M
