A chemist must prepare 550. mL of 60.0 mM aqueous potassium dichromate (K,Cr,O,) working solution. He'll do this by pouring out some 0.403
aqueous potassium dichromate stock solution into a graduated cylinder and diluting it with distilled water.
Calculate the volume in mL of the potassium dichromate stock solution that the chemist should pour out. Be sure your answer has the correct number of
significant digits.
