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

Masses :  Ca = 40.08 g   S= 32.07 g  O= 16.00 g  A 35.0 mL sample of CaSO4 was evaporated to dryness, leaving 0.967 g of residue. What was the molarity of the original solution?   step by step please

How will you separate soluble and insoluble impurities?
