Molar and molecular weight of O6PtS2

• Relative molecular weight of O6PtS2: 355.2104
• Molar mass of O6PtS2: 355.2104 g/mol (0.35521 kg/mol)

Calculation of the relative molecular and molar mass of O6PtS2

• Mr[O6PtS2] = Ar[O] * 6 + Ar[Pt] + Ar[S] * 2 = 15.9994 * 6 + 195.084 + 32.065 * 2 = 355.2104
• Molar mass (kg/mol) = Mr[O6PtS2] : 1000 = 355.2104 : 1000 = 0.35521 kg/mol
