An iron ore was analyzed by dissolving a 1.957-g sample in concentrated HCl. The resulting solution was diluted with water, and the iron(III) was precipitated as the hydrous oxide Fe2O3·xH2O by the addition of NH3. After filtration and washing, the residue was ignited at a high temperature to give 0.6009 g of pure Fe2O3. Calculate (a) the % Fe and (b) the % Fe3O4 in the sample.

Fluorine is so reactive that it forms compounds with mate-rials inert to other treatments.(a) When 0.327 g of platinum is heated in fluorine, 0.519 g of adark red, volatile solid forms. What is its empirical formula?(b) When 0.265 g of this red solid reacts with excess xenon gas,0.378 g of an orange-yellow solid forms. What is the empiricalformula of this compound, the first to contain a noble gas?(c) Fluorides of xenon can be formed by direct reaction of the el-ements at high pressure and temperature. Under conditions thatproduce only the tetra- and hexafluorides, 1.85x10^-4mol ofxenon reacted with 5.00x10^-4mol of fluorine, and 9.00x10^-6mol of xenon was found in excess. What are the mass percents ofeach xenon fluoride in the product mixture?
