3. When the first half of the solution containing NaCl and KCI, obtained from 2 g of a feldspar sample, is precipitated with H,PtCl, in an alcoholic medium, the precipitate of K,PICI, is 486 mg. When the other half of the solution is precipitated with AGNO, 430.5 mg AgCl is formed. Calculate the percentage of Na,O and K,O in the sample. (H :1 g/mol; Na : 23 g/mol; Cl : 35.5 g/mol; K: 39 g/mol; Pt: 195 g/mol; Ag : 108 g/mol; N : 14 g/mol; O: 16 g/mol)
