Agravimetric experiment was performed to determine the number of moles of sulfate that were present in a solution of sodium sulfate. in this experiment, an excess of barium nitrate was added to the solution and a precipitate formed. the resulting mixture was filtered and the precipitate was dried. the dry mass of the precipitate was measured to be 8.642 g. write the balanced net ionic equation for the precipitate reaction and calculate the number of moles of sulfate in the sample.
