Molar and molecular weight of Co2S3

• Relative molecular weight of Co2S3: 214.06139
• Molar mass of Co2S3: 214.06139 g/mol (0.21406 kg/mol)

Calculation of the relative molecular and molar mass of Co2S3

• Mr[Co2S3] = Ar[Co] * 2 + Ar[S] * 3 = 58.933195 * 2 + 32.065 * 3 = 214.06139
• Molar mass (kg/mol) = Mr[Co2S3] : 1000 = 214.06139 : 1000 = 0.21406 kg/mol

Co2S3: percent composition by element

• Cobalt (Co) = 117.86639 : 214.06139 * 100 = 55.062 %
• Sulfur (S) = 96.195 : 214.06139 * 100 = 44.938 %
