A 0.513g solid sample containing only a mixture of LaCl3 (molar mass= 245.26 g/mol) and Ce(NO3)3 (molar mass= 326.13 g/mol) was dissolved in water. Potassium iodate KIO3 was added to the obtained solution, producing the precipitates La(IO3)3 (molar mass= 663.61 g/mol) and Ce(IO3)3 (molar mass= 664.82 g/mol). The total mass of the precipitates was found to be equal to 1.1650 g. Calculate the % of LaCl3 and Ce(NO3)3 in the sample.
