This virtual lab activity asks you design and perform an experiment to determine the mass of NaCl present in the solution labeled "Unknown NaCl"

This virtual lab activity asks you design and perform an experiment to determine the mass of NaCl present in the solution labeled "Unknown NaCl". The stockroom contains some chemicals that you find useful.
For this activity, the solution viewer in the virtual lab shows only the concentration of silver ion (Ag+) in the selected solution. This mimics a common experimental situation. Techniques such as spectroscopy or electrochemistry often make it easy to measure the concentration of only a single species, such as Ag+. Chemists must then design experiments that meet their goals, while collecting data only on the concentration of that species. In this activity, you must determine the amount of NaCl in an unknown solution, using measurements of [Ag+].
The Ksp for Silver Chloride is: 1.830e-10.
Vol AgCl = 36.088 mL
Vol NaCl = 56.69 mL
Vol UNKNOWN NaCl = 102.54mL
Vol H2O = 3000.0 mL
Overall question ; What is the mass of NaCl that is present in the 'Unknown NaCl' solution? (Please use three significant figures for your answer) grams
