Question

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].

What is the mass of NaCl that is present in the 'Unknown NaCl' solution? (Please use three significant figures for your answer)  grams.


The Ksp for Silver Chloride is: 1.830e-10.

Molarity for Ag+ is 1.99181e-10.

Volume for unknown NaCl solution is 101.44mL.


Please explain each step by showing work.
