The three students were asked to calculate the identity of the metal in a particular sulfate salt. They dissolved sample of salt of 0.1472 g in the water and treated it with excess barium chloride, it is consequential in the precipitation of barium sulfate. After the precipitate had been filtered and dried, this is weighed by 0.2327 g. Each student analyzed the data independently and came to different conclusions. The Pat determined that the metal was titanium. Chris thought it was sodium. Andy reported that it was gallium. Explain what formula did each student allocate to sulfate salt?
