Calculate the volume in m) of silver nitrate solution that will be needed for the precipitation: normally the amount of silver nitrate required to precipitate all of the chloride in the sample is found by a trial and error process. However, to speed up the experiment, assume a sample mass of 0.1479 g, and that sample contains approximately 55.0% chloride ion by mass (some samples may contain more, some less), and calculate what volume of 0.100 M AgNO3 needs to...
