A student investigates various properties of silver compounds in the lab. First, the student carries out the following procedure to determine the concentration of Ag* (aq) in a solution of AgNO3(aq). The student adds an excess of 8.0 M HCl(aq) to 200.0 mL of the solution, causing AgCl(s) to precipitate. The precipitate is separated from the solution by filtering it through a pre-weighed piece of filter paper. The precipitate and filter paper are rinsed with distilled water, dried, and weighed. The data from the experiment are given in the table below. Initial mass of filter paper Mass of filter paper + AgCl(s) precipitate after drying (a) Calculate the number of moles of AgCl(s) that precipitated. (The molar mass of AgCl is 143 g/mol). (b) Assuming that all of the Ag'(aq) ions precipitated, calculate the original molarity of Ag (aq) in the solution before HCl(aq) was added. 0.10 M NaCl O = Na* OF AR 0.851 g 2.311g 7M ARNO, -NO₂ (c) lons in a certain volume of 0.10 M NaCl(aq) are represented in the box above on the left. In the box above on the right, draw a particulate diagram that represents the ions in the same volume the original molarity of Ag*(aq) in the solution before HCl(aq) was added
