12.25 g of KClO_3 and 5.85 g of NaCl ar heated together. The residue obtained at the end of burning is dissolved in water to prepare a 500 mL solution. To the solution obtained, excess of AgNO_3 is added. Find the moles of white precipitate formed. Also find the molarity of the solution after filtering out the precipitate with respect to NaNO_3 and KNO_3 (molecular mass of KClO_3 is 122.5 and that of NaCl is 58.50) |
