Molar and molecular weight of MoS3

• Relative molecular weight of MoS3: 192.135
• Molar mass of MoS3: 192.135 g/mol (0.19214 kg/mol)

Calculation of the relative molecular and molar mass of MoS3

• Mr[MoS3] = Ar[Mo] + Ar[S] * 3 = 95.94 + 32.065 * 3 = 192.135
• Molar mass (kg/mol) = Mr[MoS3] : 1000 = 192.135 : 1000 = 0.19214 kg/mol

MoS3: percent composition by element

• Molybdenum (Mo) = 95.94 : 192.135 * 100 = 49.934 %
• Sulfur (S) = 96.195 : 192.135 * 100 = 50.066 %
