A chemist must prepare 375.mL of 5.00mM aqueous potassium dichromate K2Cr2O7 working solution. She'll do this by pouring out some 11.8mmolL 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. Round your answer to 3 significant digits.
