Molar and molecular weight of Y2S3

• Relative molecular weight of Y2S3: 274.0067
• Molar mass of Y2S3: 274.0067 g/mol (0.27401 kg/mol)

Calculation of the relative molecular and molar mass of Y2S3

• Mr[Y2S3] = Ar[Y] * 2 + Ar[S] * 3 = 88.90585 * 2 + 32.065 * 3 = 274.0067
• Molar mass (kg/mol) = Mr[Y2S3] : 1000 = 274.0067 : 1000 = 0.27401 kg/mol

Y2S3: percent composition by element

• Yttrium (Y) = 177.8117 : 274.0067 * 100 = 64.893 %
• Sulfur (S) = 96.195 : 274.0067 * 100 = 35.107 %
