Molar and molecular weight of Cr2S3

• Relative molecular weight of Cr2S3: 200.1872
• Molar mass of Cr2S3: 200.1872 g/mol (0.20019 kg/mol)

Calculation of the relative molecular and molar mass of Cr2S3

• Mr[Cr2S3] = Ar[Cr] * 2 + Ar[S] * 3 = 51.9961 * 2 + 32.065 * 3 = 200.1872
• Molar mass (kg/mol) = Mr[Cr2S3] : 1000 = 200.1872 : 1000 = 0.20019 kg/mol

Cr2S3: percent composition by element

• Chromium (Cr) = 103.9922 : 200.1872 * 100 = 51.947 %
• Sulfur (S) = 96.195 : 200.1872 * 100 = 48.053 %
