Answer:
The presence of <em>silver nitrate impurities</em> is the most probable cause for the initial precipitate result.
Explanation:
In test for halide ions, silver nitrate is used to test for the presence of soluble halide ions. The presence of
in the reaction mixture (possibly the HNO3) gave the semblance of test for chlorides, allowing for formation of precipitation in the initial experiment.
This error could have been caused by handling of reagents and used laboratory apparatus during the initial reaction.

Answer:
200/3 M which is approximately equal to 66.6667 M
Explanation:
Molarity is defined as the number of moles of solute per liter of solution.
It can be calculated as follows:
We are given that:
number of moles of solute = 8 moles
volume of solution = 120 ml = 0.12 liters
Substitute with the givens in the above equation to get the molarity as follows:
molarity =
