mol aqueous L A chemist must prepare 875. mL of 10.0 mM aqueous calcium sulfate (CaS0,) working solution. He'll do this by pouring out some 0.0110 calcium sulfate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the calcium sulfate stock solution that the chemist should pour out. Be sure your answer has the correct number of significant digits.
