A 6.03 g sample of a mixture containing Fe, Pb and Ba) was dissolved in nitric acid (HNO3). The solution was then treated with sulfuric acid, H2SO4 (MM = 98 02 g/mol), which precipitated 0.729 g of PbSO4 (MM = 303.27g/mol) and 3.76 g BaSO4 (MM = 233.32 g/mol). Assuming that all of the Lead and Barium precipitated, what is the percentage of Iron (Fe) in the sample? (Fe, MM = 55.85 g/mol, Pb, MM = 207.20 g/mol AND Ba, MM = 137.33 g/mol))

Question
A 6.03 g sample of a mixture containing Fe, Pb and Ba) was dissolved in nitric acid (HNO3).
The solution was then treated with sulfuric acid, H2SO4 (MM = 98 02 g/mol), which precipitated
0.729 g of PbSO4 (MM = 303.27g/mol) and 3.76 g BaSO4 (MM = 233.32 g/mol).
Assuming that all of the Lead and Barium precipitated, what is the percentage of Iron (Fe) in the sample?
(Fe, MM = 55.85 g/mol, Pb, MM = 207.20 g/mol AND Ba, MM = 137.33 g/mol))
