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?

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.
