Balanced equation is:
Cl-+ AgNO3→ AgCl + NO3-
= 0.01274 mol Cl-
The mass percentage of chloride ion in a 26.00 mL sample of seawater was determined by titrating the sample with silver nitrate, precipitating silver chloride. It took 42.52 mL of 0.2996 M silver nitrate solution to reach the equivalence point in the titration.
What is the mass percentage of chloride ion in the seawater if its density is 1.025 g/mL? Express your answer using four significant figures.
