WebSince 0.10 grams of Ag2CrO4 is used with an excess of BaCl2, Ag2CrO4 would be the limiting reactant. The molar mass of Ag2CrO4 = (2 x 107.8682 g/mol Ag) + (51.9961 g/mol Cr) + (4 x 15.999 g/mol O) = 331.7285 g/mol. The moles of the limiting reactant can be found using this equation: 0.10 g / 331.7285 g/mol = 0.000301 mol of Ag2CrO4 Using …
