You post isn't clear as to what you want. When you say "what is the grams of chlorides" I am assuming you want grams NaCl. If that isn't so please rephrase and repost the question.
0.3 g AgCl x (molar mass NaCl/molar mass AgCl) = g NaCl
% NaCl w/v = (g NaCl/10 mL) x 100 = ?
If I have understood the problem correctly this pharmaceutical supply house is not selling good stuff.
10 ml of 0.9% physiological solution sold in the pharmaceutical trade, was treated with an excess of precipitating solution of AgNO3 to 2m, leading to the formation of a white precipitate of silver chloride (AgCl), which weighed after the realization of all the steps gravimetric 0.3 g of AgCl. What is the quantity in grams of chlorides present in the sample and what is its percentage content in the sample?
