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?

1.600 g of aluminum sulfate sample was dissolved in water and aluminum was precipitated as Al(OH)3. The precipitate was filtered, dried and ignited to form Al2O3. The mass of aluminum oxide was found to be 0.400 g. Calculate the percentage of aluminum sulfate in the sample. (Al: 27, S: 32, O: 16 g/mol)
