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

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...

Question
A 20.0 mL sample solution contains unknown amount of bromide ion (Br). To this solution was added the solution that contains plenty of AgNO3. AgBr precipitates were formed. The precipitate were filtered and measured to be is 0.6964 g. What is the molarity of bromide ion in the original sample solution? The molar mass of Br = 80.0 g; the molar mass of AgBr = 188 g. (Solution) AgNO, is soluble and thus exists Ag+ ion and NO3-ion. Ag+...
