An unknown mass of Na, o (molar mass = 61.979 g/mol) was dissolved in enough water to create a 150.0 mL stock solution. A 5.00 mL sample of the stock solution was transferred to a volumetric flask and diluted to 500.0 mL. The pH of the dilute solution is 13.27. Calculate the concentration of OHions in the dilute solution. 0.18 concentration: M Incorrect Calculate the concentration of OH ions in the stock solution. 18 concentration: M Incorrect Determine the original mass of Na, o dissolved in the stock solution. 167.3 mass of Na,o: g Incorrect
