In one gravimetric analysis, the iron (Fe) in a 1.6374 g of impure iron compound was dissolved with nitric acid, HNO3 to oxidize iron. The precipitate will be formed as hydrous compound. The precipitate was then filtered, rinsed and ignited at 900°C to give anhydrous Fe₂O3 weighed of 0.8994 g. Calculate the percentage by mass of Fe in a sample
