The gravimetric factor is the ratio of the molar mass of the analyte to the molar mass of the product. In this case, the analyte is silver cation (Ag+) and the product is silver carbonate (Ag2CO3). The molar mass of Ag+ is 107.87 g/mol and the molar mass of Ag2CO3 is 275.79 g/mol. Therefore, the gravimetric factor is:GF = (molar mass of Ag+) / (molar mass of Ag2CO3)GF = 107.87 g/mol / 275.79 g/molGF = 0.391
