Molar and molecular weight of Ag2Cr2O7

• Relative molecular weight of Ag2Cr2O7: 431.7244
• Molar mass of Ag2Cr2O7: 431.7244 g/mol (0.43172 kg/mol)

Calculation of the relative molecular and molar mass of Ag2Cr2O7

• Mr[Ag2Cr2O7] = Ar[Ag] * 2 + Ar[Cr] * 2 + Ar[O] * 7 = 107.8682 * 2 + 51.9961 * 2 + 15.9994 * 7 = 431.7244
• Molar mass (kg/mol) = Mr[Ag2Cr2O7] : 1000 = 431.7244 : 1000 = 0.43172 kg/mol
