A chemist must prepare 450. mL of 35.0 mM aqueous potassium dichromate (K, Cr,0,) working solution. She'll do this by pouring out some 0.490 M 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. mL A chemist must prepare 450. mL of 35.0 mM aqueous potassium dichromate (K, Cr,0,) working solution.
