1.	0.9031g of mixture of NaCl and KCl on treatment with conc. yields 1.0784g of a mixture of and . Calculate the % composition of the mixture.
Answer» the mixture = 0.9031 g Let the mass of NaCl = x g The mass of KCL = (0.9031 - x)) g From EQUATION (i) From equation (ii) 149 g of KCl gives 174 g of Therefore, On solving, x = 0.518 g Mass of NaCl = 0.518 g Mass of KCl = 0.9031 - 0.518 = 0.3851 g
