Describe how you would prepare a 500 mL of a solution which is 0.500 M sodium and 1.60 M phosphate if you only had sodium chloride and potassium phosphate available? NOTE: The chloride and potassium ion concentrations in the final solution are unimportant. ANSWER OPTIONS: A) Add 14.61 g NaCl and 169.78 g of potassium phosphate to 500 mL graduated cylinder and fill to the 500 mark. B) Add 5.75 g of NaCl and 76.0 g of potassium phosphate to a 500 mL volumetric flask and fill with distilled water to the mark. C) Add 14.6 g of NaCl and 170. grams of potassium phosphate to a 500 mL volumetric flask and fill with distilled water to the mark. D) Add 14.6 g of NaCl and 170. grams of potassium phosphate to a 500 mL graduated cylinder and fill to 500 mLs.
