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...

You obtain an unknown with an approximate chloride mass% of 51%. Calculate the volume (in mL) of 0.29M silver nitrate you need to add to 0.2915 grams of unknown to ensure full precipitation. Your calculation should assume that you add 28% excess silver nitrate. Give the answer with the appropriate number of significant figures and the correct units. Silver nitrate molar mass: 169.87 g/mol Chloride molar mass: 35.45 g/mol
