2) You are tasked with determining the barium content of a sample containing barium nitrate mixed with rubidium nitrate. The sample is weighed, dissolved into 50.0mg water, and treated with xs 0.500M sodium sulfate. The acid fully ionizes in this experiment. A white precipitate forms which is washed, filtered, and weighed multiple times, according to the data given below: Mass of sample 0.425g Mass of thoroughly dried filter paper 1.462g Mass of precipitate+filter after 1st drying 1.755g Mass of precipitate+filter after 2nd drying 1.699g Mass of precipitate+filter after 3rd drying 1.698g C] In the filtrate solution, is [Na'] less than, equal to, or greater than the [NO,] level? Justify your answer.
