A mixture contains only NaCl and Fe(NO3)3 . A 0.456-g sample of the mixture is dissolved in water, and an excess of NaOH is added, producing a precipitate of Fe(OH)3. The precipitate is filtered, dried, and weighed. Its mass is 0.107 g. Calculate the following. a. the mass of iron in the sampleb. the mass of Fe(NO3)3in the samplec. the mass percent of Fe(NO3)3in the sample
