A chemist must prepare 975. mL of 160, mM aqueous sodium carbonate () working solution. He'll do this by pouring out some 0.174 mol/L aqueous sodium carbonate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the sodium carbonate stock solution that the chemist should pure out. Round your answer to 3 significant digits.
