WebA chemist added an excess of sodium sulfate to a solution of a soluble barium compound to precipitate all of the barium ion as barium sulfate, BaSO4. How many grams of barium ion are in a 458-mg sample of the barium compound if a solution of the sample. 2 answers; AP Chem; asked by Anna; 3,830 views; The Ksp of PbBr2 is 6.60× 10^–6. Webm = 6 l × 998 kg/m³ = 0.006 m³ × 998 kg/m³= 5.988 kg. It's easier to work with grams, so convert the mass: 5.988 kg = 5988 g. As you already know how the grams to moles conversion work, find the number of moles: n = 5988 g / 18.015 g/mol = 332.4 mol.
