STOICHOMETRY Dilution A chemist must prepare 1000 ml of 5.00 mM aqueous copper(IT) fluoride (CuF) working solution. He'll do this by pouring out some 0.00579 M aqueous copper(11) fluoride stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the copper(II) fluoride stock solution that the chemist should pour out. Be sure your answer has the correct number of significant digits.
