The iron, tin, and titanium in a sample were jointly precipitated as hydroxides, which were washed and ignited to produce Fe₂O3, SnO2, and TiO₂. This mxture of oxides, which amounted to 0.3768 g, was dssolved after fusion with potassium pyrosulfate. Analys s showed that 0.0322 g of Ti was present. The ron was determined separately as an oxide: 0.1837 g FeO was found. What was the weight (mass) of tin in the sample?

Use the References to access important values if needed for this question. Mn, S,O, n H20 is the general formula of a certain hydrate. When 347.2 g of the compound is heated to drive off the water, 217.4 g of anhydrous compound is left. Further analysis shows that the percentage composition of the anhydrate is 36.38% Mn, 21.24% S, and 42.38% O. (Hint: Treat the anhydrous compound and water just as you have treated elements in calculating X in the formula of the hydrate.) (Use an asterisk to enter the dot in the formula. If a subscript is 1, omit it.) a. Find the empirical formula of the anhydrous compound. b. Find the empirical formula of the hydrate.
