Hi... I x-posted this to the other chemistry board..but that might've been the wrong place...
I recently performed an experiment to determine the % Cl (by mass) of an unknown chloride sample containing both potassium and sodium. To determine this, we did a Fajans method titration using 0.1 M AgNO3.
A 1.0233g sample of the unknown chloride sample was diluted and titrated with the silver nitrate. Approximately 15.70 mL of the silver nitrate was used.
Okay, so, I understand that to determine the % Cl by mass, I should determine a final mass and divide it by the original mass of the entire chloride sample. This may seem like a stupid question, but what final mass are we determining? From the total volume of silver nitrate used, I can figure out the moles of silver nitrate used. Where do I go from here?
Please help me!
Thanks,
Heather
