A" " 5.0 g sample of felspar containing Na_(2)O,K_(2)O and some inert impurity is dissolved in dilute HCl solution and NaCl and KCl formed are separated by fractional crystallization. During crystallization some less soluble impurities also come out. Mass of NaCl, KCl and impurity accompanying these salts was found to be 6.47 g . Solid crystal was then re-dissolved and required 300mL of 0.3M AgNO_(3) for complete precipitation of chlorides. The precipitate this, obtained ws found to contain 4.23% insoluble impurity. Determine mass percentage of Na_(2)O and K_(2)O in the original sample:
