How many grams of NaCl (OR "N" a Cl) would be required to prepare a 0.460 M solution with a volume of 323.00 mL?
Do not type units with your answer.
323.00 mL x (0.460 M / 1000 mL) = 0.149 mol NaCl
Molar Mass of NaCl = (Na-22.990 + Cl-35.453) = 58.443
0.149 mol NaCl x (58.443 g NaCl / 1 mol NaCl) = 8.71
